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've updated our S,M and L sizes based on your feedback. Please refer to the size guide.

It was a slightly slimmer fit than other Cos tops of this style that I have, but as it's for layering, that's not a problem. I always like the thumb holes. It's more Winter white than bright white in colour though.

I am a US size 10, and I got this long sleeve in Large, and I had no problems with it being too baggy like other reviewers.  It fits me just right.  Considering that it is mostly cotton, it does feel a bit synthetic, but not in a bad way.  It is very soft and pleasant to the skin.  An essential layering piece.

i am tall and slim and I love how the sleeves reach the ends of my arms and the torso is long enough to keep my middle snug. I now own one in each colour.

Given that the website has a find-my-size feature and that the shirt is advertised as "slim", I did not expect the sizing to be as far off as it was. I am 5'10", 160lbs, with 31" waist and 39" bust. I got a size Large based on the website recommendation, but it fit me like a sack.  I did appreciate that the sleeves were actually long enough for my arms, which is rare, and the torso was long enough to easily tuck in, but I had to return due to the overall fit. I am going to try a medium or small next to get the fit I want for layering under other garments.
