Consistent quality, reliable store

I've bought from COS several times before, and this order for a wool coat was just as good as previous ones. The sizing is always consistent for me, which I appreciate. Delivery was standard, around a week to the East Coast. I keep coming back because their designs are timeless and the quality holds up well over time. No surprises, which is a good thing when shopping online. It's my go-to for essentials.

Worth it with the discount

I was looking for some new wardrobe staples and found COS. This was my first time buying from them. I got a poplin shirt and wide leg pants during their mid-season sale. The 20% off made a big difference for me. Shipping was free and got here in 6 days. The clothes feel well-made and not flimsy. I probably wouldn't pay full price for everything, but with a sale, it felt like a smart buy. It was worth it for the quality I received.

Good quality, fast shipping

I ordered a cashmere sweater. It arrived quickly, took about 3 days to get here. Quality is really good for the price. Happy with my purchase, no complaints.

Overall good, but sizing was off

My recent order included a pair of tailored trousers and a silk shirt. The shirt's quality is excellent, soft and feels expensive. The trousers, however, ran a bit large, which was a hassle. I had to exchange them, which was easy enough but added a delay. Customer service was helpful with the return process. Value for money is decent, especially with their seasonal sales, but watch the sizing.

Hey, thinking about grabbing a few things from COS, specifically some of their tailored stuff like trousers and a blazer. how's the sizing generally? i'm usually a US 8, wondering if I should size up or down for a better fit.

E Emma Silva 3 months ago
From my experience with their dresses and tops, they tend to run a bit generous, especially for the oversized styles. I'm usually a 6 and often go down to a 4 there. For tailored pieces though, it might be more true to size, but I'd still lean towards your usual or even a size down if you like a slimmer fit.

Yeah, I agree with the other commenter. Their stuff is definitely on the roomier side. I got a knit vest a while back, and my usual size was huge on me. Ended up returning for a smaller one, and that was perfect. Returns were pretty easy, btw.

Quick question for anyone who's ordered from COS recently for delivery to, say, California. how long did it actually take for your order to arrive? the website says one thing, but sometimes it's way different.

I'm in LA and my last order, a couple of poplin shirts, took maybe 5-6 business days total. That was standard shipping, didn't pay extra. It was pretty much what they said it would be.

Hmm, I'm up in NorCal and I remember my trench coat took almost a full 7 business days, maybe a bit more. It wasn't super fast, but it got here eventually. I think it depends on stock sometimes too.
