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.

Is COS.com a legitimate website? Saw some really good deals on a trench coat.

A AnkitSharma 5 days ago ✓ Best Answer

Yes, COS.com is their official site. They're part of H&M group. Totally legit.

R RituDesai 5 days ago

Okay, good to know. The prices seemed almost too good.

G GeetaVerma 5 days ago

Just make sure it's actually COS.com and not a similar-looking site. Scammers are everywhere.

M ManishGupta 5 days ago

They have sales fairly often, especially end of season. So good deals aren't unusual.

R RituDesai 5 days ago

That's what I was hoping. Thanks!

Can I return an online COS order to a physical store in the US?

S SoniaGupta 1 week ago ✓ Best Answer

Yes, you can! Just bring your packing slip or order confirmation. I do it all the time.

R RajeshKumar 1 week ago

Awesome, that saves me a trip to the post office. Thanks!

V VikramShah 1 week ago

Yup, did it last week with a midi dress that didn't fit.

M MeenaPatel 1 week ago

Just make sure it's within the return window. And they'll process the refund back to your original payment method.

R RajeshKumar 1 week ago

Got it, thanks for the heads up.

Anyone know if COS does price adjustments? Just bought a wool coat and it's on sale now.

M MeeraSharma 3 weeks ago ✓ Best Answer

They used to, but policies change. Worth a shot, but don't get your hopes too high if it was a big markdown.

N NehaJain 3 weeks ago

Ugh, figures. It's a pretty good markdown now.

R RohanGupta 3 weeks ago

Could always return and repurchase if it's within the window. More hassle though.

S SanjayMalhotra 3 weeks ago

I think they do within 7 days, but you usually have to contact them directly. Not sure if it's a guaranteed thing.

N NehaJain 3 weeks ago

Thanks, I'll try calling. It's only been 3 days since I bought it.

My COS student discount isn't working at checkout. Anyone else?

D DeepakKumar 1 month ago ✓ Best Answer

Are you trying to use it on sale items? Usually doesn't apply to those.

S SnehaGupta 1 month ago

Yeah, learned that the hard way during the end of season sale.

P PriyaSharma 1 month ago

Oh, that could be it! I have a few sale pieces in my cart. Didn't think of that.

A AnjaliSingh 1 month ago

Mine worked last week. Did you make sure it's linked to your UNiDAYS account properly?

P PriyaSharma 1 month ago

Yeah, it's linked. I even tried re-verifying.

R RahulMehta 1 month ago

I had to try a few times. Sometimes it's glitchy.

Got a first order discount code from signing up to the newsletter, but it's not working. Help?

V VijayKumar 2 weeks ago ✓ Best Answer

Did you check the exclusions? Sometimes it's not valid on certain collections or sale items.

A AishaKhan 2 weeks ago

I'm buying a regular-priced cashmere sweater. Nothing special.

D DivyaReddy 2 weeks ago

Make sure you copied it exactly. No extra spaces or anything.

G GautamMehra 2 weeks ago

Mine expired really fast once. Is there an expiry date on the email?

A AishaKhan 2 weeks ago

It says it's valid for 30 days. I just got it yesterday.

How do COS sizes run for their wide leg pants? Should I size down?

A AnuMishra 1 week ago ✓ Best Answer

Definitely size down. Their wide leg stuff is usually very generous. I'm usually an 8 and wear a 6 in their pants.

K KaranSingh 1 week ago

Yes, second this! Especially the tailored ones, they run big.

S ShrutiPandey 1 week ago

Thanks! That's super helpful. I hate returning pants.

R RinaChopra 1 week ago

Depends on the specific cut. Check the garment measurements if they have them on the product page.

S ShrutiPandey 1 week ago

Good point. I'll take a look.

My order from the Archive Sale is still showing as 'processing' after 5 days. Is this normal?

K KavitaRao 3 weeks ago

Mine took ages during the last sale. I think they get swamped. Give it another few days.

V VivekDesai 3 weeks ago

Same experience here. My tracking only updated after a week.

A AmitPatel 3 weeks ago

That's good to know. I was starting to worry.

P PoojaShah 3 weeks ago

I'd email customer service. They usually get back within a couple of days, even if it's just to say it's delayed.

A AmitPatel 3 weeks ago

I sent an email yesterday. Still waiting to hear back.

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.

S Sam Brooks 3 months ago

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.
