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.

I ordered this dress in size 8P and they are extremely long on me — well below the ankle. I’m 5'2", and the proportions feel completely off. The fit also sits strangely at the top, with extra fabric that doesn’t lie flat. COS sizing continues to be inconsistent, and it makes shopping difficult. If the sizing varies this much, shipping and returns really should be free.

i cannot believe how much I love this dress.  There was some concerns over ordering it because of the open back, but it is quite flattering.  The green color is gorgeous.  It’s in the to be packed stack for summer vacation.

Beautiful dress. Excellent quality. For me perfect length, long legs for 5ft 6. For those of shorter stature would be floor length

Waist below and length are ok but the chest area is too tight for me. I ended up returning the item.
