Although we think of our sizing as a starting point with certain pieces, it really does matter how you want the particular piece of clothing to feel and fit on you. Particularly with our jersey fabrics...there's a lot of give, so you may find you can wear more than one size, but the fit will be quite different. Choose the option that makes you feel your best!
As a general rule, the drape neck jersey tops have a little more give than the cross-front jersey tops, which are more fitted. The woven materials (e.g. rayon) run true to size and have no give at all.
Each product has a "Size Chart" link at the bottom of the product description for additional measurement detail.
