Quick answer: The same bust, waist, and hip measurements can feel different in a stretch and a non-stretch qipao. Check the lining and test movement as well as standing fit.

A size chart is the starting point, not a promise of comfort. A dress may smooth over the body while standing yet pull at the hips when you sit. The outer fabric may stretch while the lining does not.

Ask what “stretch” means

Check the fiber content, whether the fabric stretches across the body or in another direction, and whether the lining has similar give. A little stretch at the waist does not guarantee freedom at the shoulders or armholes. Non-stretch fabrics need enough room at the bust, hips, shoulders, and upper arms for the movements you expect. Tightness should not be mistaken for a good fit.

Test the size in motion

Sit in a chair, walk, and reach for an object. Watch for strong horizontal pulling or seams under strain. Before ordering, ask whether the chart lists body measurements or finished garment measurements, and whether both outer and lining fabrics stretch. Compare those answers with your own measurements and the return policy.

Avoid choosing by recommended weight alone: people of the same weight can have very different proportions. If you fall between sizes, ask about ease at the areas that matter most and whether minor alterations are possible.
