Absolutely love the Solene bikini

Absolutely love the Solene bikini! The fit is incredible, especially for someone with a bigger bust. The adjustable straps at the back make it so easy to get the perfect fit and feel really supported. The quality of the material and the design are amazing, you can really tell a lot of thought has gone into it. I’m so happy with my purchase and will definitely be re-ordering the blue version as well. Highly recommend!

Great service, very easy purchase and helpful!

I ordered three bikinis for my girlfriend from Mia Swim at the start of February ahead of our holiday on the 18th, and what a lovely customer service team.

I was a bit unsure about sizing as I was ordering for her, so I messaged customer service for some help. They were really friendly and took the time to go through her measurements with me and recommend the best size. My girlfriend had shown me a few styles she liked on the site before, so I had an idea of what to get - just wanted to make sure I got the size right!

When the bikinis arrived the quality was great and the colours looked exactly like they did online. One of the pieces needed an exchange as we needed to size up in the top (bikini name: Acapulcho), but the team sorted an exchange express delivery, which I massively appreciated as we were due to leave in a few days!

My girlfriend absolutely loved them, the styles really suited her and she’ll definitely be ordering more herself.

Overall really great customer service, quick help with sizing and a really fast exchange when we needed it. Would definitely recommend!

Absolute favourite bikinis

Absolute favourite bikinis! If I could give more stars I would. I ordered the Solene bikini in Blue as I already have the Pink (it’s literally my go to). The fit, the quality is incredible, really impressed! The ordering and delivery process is super easy 10/10 ❤️ love this brand

So helpful and easy exchange!

So helpful and fast! I added the wrong email address to my order so I wasn't getting any updates and so I contacted customer service and they updated my email address and all was sorted within a few hours. I don't usually leave reviews but I saw the Solene bikini on an ad and it looked so beautiful on the model so I thought I would order. It did not disappoint, as a bigger bust, smaller band girly (size 32G) I ordered an XL top and it fit perfect! The bottoms were slightly smaller so I ended up exchanging for a bigger size, this was free and easy! Honestly, thank you so much, I wish you did this bikini in more colours!! Definitely recommend and ordering again from you guys!

Unhelpful customer service and slow refund

Bikini didn’t fit at all (I should have known better as even in the Instagram advert the bikini didn't fit the girl properly across the back and she had to pull it really tight). But I gave them a shot, wanting to support a small business, but the customer service has been appalling. I paid for delivery postage, return postage (ok, I accept these) but then despite having confirmation from Royal Mail tracked that the parcel had arrived back with Mia Swim (thank goodness I paid for tracked) I didn't receive my refund for 2 weeks and that was only after chasing them via customer service. The responses were generic "Emily x" and unhelpful, particularly when the refund did then arrive but £1 lower than the amount I paid for the bikini (due to "bank charges"??). I have never had this type of excuse from any other small brand and their lack of helpfulness on this final point has confirmed that I will unfortunately never recommend them or buy from them again and would recommend anyone reading this doesn't either unless you want to waste money!

Complicated / unclear returns process

Like others I saw their advertisements on Instagram, wanted to support a small business. The bikini arrived after about one week. While the bikini is a more bold colour than expected, it's a pretty bikini and resembles the online images. However it doesn't sit right on me, so I need to return it. I requested a return online, which is seems they have to approve manually? That took another week, but the return slip says you have to return with 14 days. Lack of clear return instructions - seems you need to send as regular post. Initially couldn't find the return address as it's written in microprint with a matrix printer, so hard to see! I appreciate they are a small business, but putting clear instructions on their website and on the packing slip should be doable.

Hi Hannah,

Thank you for your feedback!

We’re glad to read you liked the bikini but sorry to hear it doesn’t sit right! Please see our returns process on our website under ‘returns policy’ and it’s printed on the slip in your parcel (including the returns address).

We are a small business and haven’t had the chance to upgrade our system to what is seen on the likes of ASOS. This is something I would love to sort in the near future. Our returns process does work, however, and we process them as soon as it’s received.

If you wish a size exchange, we’d gladly arrange this for free, but appreciate it may be more a style element.

Terrible customer service

The customer service of this brand in my experience has been appalling. Lack of response on their online chat and even through their socials when I hadn’t heard back in over 2 weeks. I’m stuck with a bikini that doesn’t fit that I can’t return - waste of money.

Hi Louise,

We received your message on 25th October saying you loved the colour and designs of our bikini and missed the cut off to return due to the reason you listed.

We did reply to your chatbot message, however, sometimes if you go off the site before we respond you won’t have received our message.

We have now sent you an email with a possible resolution, we hope will be favourable!

Poor customer service

Poor customer service. The order missed the delivery SLA and didn’t arrive in time for my holiday. I returned the bikini and have yet to receive a refund 3 weeks after the return was delivered back to them.
I wouldn’t recommend ordering from this company.

Hi Natalie,

Thank you for your feedback!

Our standard delivery time is 3–5 working days, and we also allow up to 24 hours to prepare your order and have it collected by EVRI. Based on this, your delivery did arrive within the expected timeframe outlined on our website.

We’re sorry to hear that you were still disappointed!

Regarding the return, we were unable to process it in the usual way because a chargeback was raised from you. Once that happens, we must follow the bank’s procedure, and the funds are held by your bank until the process is completed.

Hi Tiffany,

We’re sorry to hear you felt there was a lack of communication, however, looking back at our chain we did reply promptly! Your first email was on 1st October at 9:47am, and we replied the same day at 11:20pm. You then emailed again on 6th and 7th October, and we responded on 7th October at 11:42pm. When we didn’t hear back within 48 hours, your parcel was replaced free of charge to make things right. Further emails were exchanged on 20th, 21st, and 25th October, showing consistent communication throughout. You DM’d us on 16th and 17th and we responded within 48hrs replying to you on 18th.

As a small business, I always aim to respond promptly and provide updates where I can.

Replies are slow

I saw an advertisement on Instagram and wanted to support small.
I brought two bikinis from them as I wasn’t sure on sizing. They came just in time for my holiday, however they didn’t sit quite right on my shape.
They were great quality and so cute so I was a little gutted.
I returned them and they contacted me to ask if I wanted an exchange. I responded after my holiday requesting just a refund - which to be fair to them was almost two weeks later - but I never heard back from them.
A whole month after they actually received my return they email me a refund receipt.

Hi Ella,

Thank you for your review.

As noted in our latest email, we sent you a refund receipt on 4th September, shortly after receiving your return.

We’re sorry if you were unable to see this email at the time, but please rest assured it was sent to the address linked to your order.

Thank you also for your kind words about the bikini, we truly appreciate your feedback and hope you shop again with us in the near future.

Non existent customer service

Purchased this bikini 5 days before a holiday and paid extra for the quicker delivery. The bikini unfortunately didn’t arrive prior to my holiday and was delivered whilst I was away. As soon as I returned (14 days later) I tried on the bikini (which I loved!) but the bottoms didn’t fit. I immediately requested a return which was instantly denied by the company simply because it was out of their standard timeframe. I tried contacting again justifying why I requested the return and if they would reconsider and I have heard nothing. Very poor customer service and communication, which is such a shame because if they’d let me return the bottoms I’d purchase them again in a different size!

Hi Evie,

We're so glad you loved the Bikini!

We’d like to highlight the email you sent to us on 6th July, where you mentioned a delivery error of your first email that prevented us from receiving this correspondence. We responded promptly on 8th July, offering to ship a replacement in your preferred size for the bottoms, but unfortunately, we did not receive a reply.

Regarding your return request: please note that our system automatically declines requests that are not submitted within 14 days of delivery. As long as the tags are still intact, we’re more than happy to send you the correct size in the bottoms. I’ve also sent a follow-up email to our response sent on 8th July.

I got the Kea Bikini, it is so flattering! I always struggle with bikini sizing especially on my bottom half but these fit me perfectly and the quality feels great too. Sooo happy, looks exactly as described. Fast delivery and checkout was efficient, definitely will reorder.

Hi Ellie,

We’re sorry to hear the bikini didn’t meet your sizing expectations, and we really appreciate you sharing this feedback.

In terms of returns, we don’t charge a fixed return fee — the cost is covered by the customer via a courier of their choice. Typically, using Royal Mail or EVRi with a tracked service should come to no more than £4. I'm unsure which courier you selected, but I hope this helps clarify our process.

Do not buy from this company

Worst experience ever. Do not buy from this brand. I ordered two bikinis with express shipping in time for a holiday (it said 1-2 days delivery on the website but frustratingly but my email confirmation said 3-4 days delivery). I emailed customer service when they didn’t arrive in time and they were understanding and offered to resend the order and refund the shipping and provide a discount which I was happy to accept. I asked for tracking details and then I heard from them a further two times when all they did was ask if I’d received the package and ignore my requests for tracking details and a status update on what was going on. I emailed countless times for an update over the next few weeks and heard nothing and still have not received my order. I am now having to take it up with my credit card company. Do NOT buy from this company. They are happy to take your money but not actually provide any form of customer service. Incredibly disappointing.

Hi Harriet,

We’d like to offer some clarity around your order.

When you placed your order with express shipping, our website did state a 1–2 business day delivery window. However, as outlined on our Delivery Policy page, this timeframe does not include our processing and packing times — something we understand may have caused confusion.

After you reached out to let us know your order hadn’t arrived in time for your holiday, we responded promptly — offering to reship the items, refund your shipping fee, and provide a discount, which you kindly accepted. The replacement was shipped using a non-tracked service at that time, but we did provide proof of postage.

According to our records, the items were ultimately delivered. However, a chargeback was initiated with your bank, and the funds were returned to you — while the products were still retained. As a small business, this has been understandably disappointing, particularly as we made every effort to resolve the situation in good faith.

We truly value our customers and pride ourselves on delivering great service. In cases like this, where the products have been received and the payment reversed, it does make things especially difficult for us.

Low quality, good customer service

I ordered 2 colours of the same bikini, maybe I got unlucky with this style as the material felt very low quality and thin (Ischia bikini). I paid for express shipping but one of the bikinis was sent a week later than the first one, not sure why. Customer service was quick and refunded my order except for shipping cost, however I wouldn’t order from here again
