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.

Silk is a delicate, natural protein fibre obtained from the cocoons of silkworms.

Lyocell is a regenerated cellulose fibre commonly made from wood, but the raw material could also consist of other cellulosic materials.

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

I like the high waist. They drape nicely. The silk mayerial  is lovely. Very cooling in hot weather as they fit loosely over your legs. As I am short I always have to take the length of  trousers up.  They are just what I was looking for.  I am a size 10 and the fit was perfect.. I also have the straight leg silk trousers in black.
