What is the difference between plus size and regular sizes?

Plus sizes are designed with different proportions than regular misses sizes. Plus sizes have more room in the bust, waist, hips, and often longer torsos. They're cut to accommodate fuller figures rather than just being scaled-up versions of smaller sizes.

A plus size XL is not the same as a regular XL. Plus sizes are cut differently—with more room throughout and different proportions. Don't assume standard XL will fit the same as plus 1X.
