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.

One of my favorite style dresses from COS.

The fit is ok...but the bottom part is super see thru.

i like the other style of the tiered midi dress where there wasnt any scrunches (navy)

Beautiful dress. I'm only 5ft 2in and it's the perfect maxi length. Lovely for the warm summer weather. I purchased the size xs

Nice color and design. Look both good in size 4 and 6. However, my chest feels tight with size 4 (32D).  I kept the larger one. Hope it helps.
