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'.

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.
