Customer Reviews
Good value on sale
I bought a knit top during their archive sale, got like 40% off. For the price, it was a solid deal. Shipping was regular speed, nothing super fast but not slow either. Definitely felt like I got my money's worth, which is always good when you're trying to save a bit.
Cute slip dress
I got a slip dress from SIR. for a party last month. It fit really well and felt super nice. It took about a week to get here, which was fine. Overall, I was happy with it.
Obsessed with my new swimsuit!
I just received my new one-piece swimsuit from SIR. and I'm completely in love! The fit is perfect, and the fabric feels so luxurious. It arrived quicker than I thought, took 4 days to get here. I'm already planning my next purchase, maybe a matching set. You guys have to check out their stuff!
Smooth order, good quality
I ordered a black backless dress. The ordering process on the website was straightforward, no hiccups at all. It shipped out in 2 days and arrived at my door in Chicago on the 6th day via standard shipping. The dress itself is made from a good quality fabric, feels soft and has a nice weight to it. I contacted customer service with a question about sizing before I bought it, and they replied within 24 hours with helpful advice. Everything was as expected, no surprises which is what you want with online shopping.
Consistent quality always
This was my third order from SIR. I got a pair of tailored trousers this time, and they're just as good as the linen dress I bought last year. The sizing is always reliable for me, and the delivery is pretty consistent, usually within 5-7 business days. It's why I keep coming back.
Nice dress, slow delivery
I purchased a floral midi dress and the material and cut are lovely. It definitely lived up to the product photos. However, the delivery took longer than I anticipated, about 10 days to reach me in California. I understand delays happen, but it was a bit frustrating waiting for it. The packaging was neat and the dress arrived in perfect condition, so that was a plus. Good quality overall, just wish shipping was a bit faster.
SIR Community Discussion
Share tips, ask questions & help fellow shoppers save more
Are their linen dresses worth the price? Like, is the quality actually good or am I just paying for the brand name?
Can I use that 10% off new subscriber code on something that's already in the sale section? There's a dress I really want but it's on archive sale.
Anyone know how long shipping takes to New York City? Trying to get something for an event next month.
Does anyone know if SIR. ever has bigger sales, like 40-50% off? I really want one of their blazers but it's a bit pricey.
what's their return policy like for US customers? Is it a pain in the butt or pretty straightforward?
