Terrible quality
Terrible quality, not as expected or advertised. Returns policy is appalling, not only do you get a comically short period of time to make a return, but the postage is almost as expensive as the actual product, making it a complete waste of time and money to even try and make a return. I would not recommend buying from this company.

Hi Eve,
We are sorry for your experience, this is of course not how it should be.
At the moment, the return policy is such that you have to pay for it yourself if you live outside the EU, as there are strict customs regulations. However, we will take your feedback into consideration.
You are always welcome to contact our customer service in connection with returns, complaints or anything else - they will be happy to help you find a solution.

Nice clothes, but sizing & delivery could be better
I like DesignbySi’s stuff — the styles are cute and material feels solid. But my pants were way too small, delivery took longer than expected, and returns felt like a hassle. Good, but needs tweaks.

Perfect school and everyday bag
I ordered a bag and it came super fast even though I’m in another country. The bag came perfectly packaged and it is identical to the pictures shown on the site. It is beautiful, spacious and very well made. I’ll use it for both school and as an everyday bag

I love this brand so much
I love this brand so much, they truly have amazing pieces, and has become my go to when i need new pieces for my closet. Everything i own from them have hold their structure and shape, from clothing to slippers. Their knitts are also so comfy and cozy, but they lock put together and stylish!!!! Could not recommend more🩷 and as a plus, they’re shipping is extremely fast, at least if you live in Norway as well, I don’t think they have ever used more the 4 days before I got my order

Great quality clothes, 10/10 customer service and no customs charge for UK customers (£100)!
I’ve bought from design by si on 2 occasions. Both times their delivery has been timely, items are great quality and well-made (exactly like the photos) and their customer service is amazing - very quick and helpful when answering queries. TO NOTE - I am based in the UK and paid no customs duties on my order of £100 - Thank you design by si covering customs fees! I will definitely be shopping again :)

Amazing!❤️
I have bought four pairs of suit pants from Design by Si and they certainly did not disappoint. In fact they are the best pants I have ever owned. Seriously! They are true to size and are perfect for a put together look! At the same time they are unbelievably comfortable. In other words, definitely worth the price. I will surely turn to Design by Si the next time I need new pants!😍
