Common questions
Before you hit buy.
Why does costume sizing vary so much?
Costume brands use different patterns, materials and size conventions, so the measurements on the specific listing matter more than the size name alone.
What measurements should I check?
Chest or bust, waist, hips, inseam or length, and height are common measurements, depending on the garment style.
