Customer Reviews
Comfy Magic Trousers
I got a pair of the Magic Trousers the other week. They're super comfy, like, way more than I expected. They fit really well too, which is always a gamble online. Shipping took about a week, which was totally fine. I'm thinking of getting another color soon.
Good quality, delivery a bit slow
I ordered a Lagenlook Tunic and a pair of the Magic Shorts. The quality of both items was pretty good for the price. The tunic drapes nicely and the shorts are surprisingly versatile. My only small gripe was the delivery; it took about 8 days to get to me, which felt a little long compared to some other places. Everything was packaged well though, and the items looked just like the pictures.
Great value on a Sale item
I was looking for a good deal on a new jacket and saw they had a clearance sale. Picked up a Denim Jacket, and honestly, for what I paid, it's really good value. I compared prices on a few sites, and this was definitely the best offer for something similar. The quality is solid, doesn't feel cheap at all. Definitely felt like I got my money's worth, especially with the discount.
Always reliable for basics
This isn't my first order from Si Sis UK. I bought a couple of the Cotton T-Shirts this time, and like before, they're exactly what I wanted. I've bought their Magic Trousers and some knitwear in the past too. The sizing is always consistent, and the quality holds up well after washing. Delivery was about the same as my last few orders, no surprises there. It's why I keep coming back when I need some dependable pieces.

Share tips, ask questions & help fellow shoppers save more
I'm thinking of ordering a few things for a holiday but I'm worried about returns if they don't fit. How easy is their return process?
Does Si Sis UK actually ship to the US? I'm in New York and really like a few of their dresses but it's a UK site so not sure.
Is this store legit? Like, are the clothes good quality or is it just fast fashion stuff that falls apart after one wash?
Hey, I've got a 10% off code from signing up to their email list, but I also see they have a clearance sale on. Can I use my 10% on a sale item?
Hey guys, thinking of grabbing some of those magic trousers. I'm usually a size 14, will they fit ok or are they super tiny sizing?
