Nasty Gal velvet blazer suit pants S

Nasty Gal fuchsia velvet suit Both pants and blazer are size 6 however I feel like the whole suit fits like a usual size 4. I have never worn a size 6 in anything and this fits like I would want it to. The pants have never been worn and still have tags attached. Blazer has been worn one time. Pants waist measurement is 13.5 and inseam is 33.5
