We are really pleased to offer you a great range of fashion with a wide selection of cosmetics. However, a few of our cosmetics contain flammable substances and therefore have delivery restrictions. Eg. nail polish, certain perfumes and nail polish removers as well as pressurised spray cans. At the same time, all our beauty items are tested to ensure that they are safe to use. It's only if you wish to return or exchange items containing flammable substances that you need to be aware that there are special transportation requirements.

HOW TO MEASURE GARMENT

It's just as easy to return a nail polish as it is to return a pair of jeans.

The easiest way to return any beauty product classified as dangerous goods is to use the original parcel because it already has the LQ.

Dangerous goods label (pictured below). Just make sure to fill the box with paper or filler so the product will stay in place.

We have added this information due to new EU regulations and to give our customers greater transparency about how product prices change over time. Under EU price display regulations, any announced price reduction must indicate the lowest price for a product in the last 30 days – we refer to this as 'lowest historical price'.

We've updated our sizes based on your feedback. Please refer to the size guide.

Runs big, meant to get 1 XS and 1 S but ended up with two small

I wish the neckline were a little closer, but I guess it does look like the one in the photo. The fabric and color are both really nice.

I'm usually an S for any other brand, and I haven't bought from COS in a while. I have longer arms, so I was very surprised when I bought this shirt and it somehow had long sleeves on me.

Fits perfectly, will go well with a million outfits.

It's the perfect basic long sleeve. It feels just right- not too tailored, and not oversized. The best part is the length. After washing, it doesn't turn into a crop top. I like my tops a little longer, and it's hard to find that in a good basic.
