Disguise Sally Glam Costume, Multi

I purchased a medium but it states size 8 to 10. I am a 12 normally but it is way too small

This dress would have looked so adorable if it wasn't for the back, it makes this an obvious costume and not a cute dress, I will have to find a long cardy to cover the zip & the fact the pattern just stops on the side, the dress came with a wig, this isn't usable, it's literally red pieces of string sewn into a rag with elastic that doesn't stay on and has huge bald patches

Cute dress but way too short and size M is more like a size S! The wig is poor quality (a red cap with a few wool strands). Not worth the money paid.
