Button-down shirts can pull at the bust or chest even when the waist fits, so check garment chest width when available.

How to measure before choosing a size

Measure over light clothing or underwear and keep the tape parallel to the floor.
For tops, jackets, and dresses, start with bust or chest, then check waist and hips.
For pants and jeans, prioritize waist, hips, rise, and inseam instead of the label alone.
If you are between sizes, choose by garment fit: size up for structured pieces and compare stretch for knit items.

FAQ

How do I measure for a jacket?

Measure around the fullest chest or bust, then check waist, shoulder width and sleeve length if available.

Should jackets be one size bigger?

Not always. Size up when you need layering room or your measurement is at the top of the range.

Are jacket sizes the same as shirt sizes?

They can be similar alpha labels, but jackets usually need more ease and may use chest-number sizing.
