The most fitted part of all dress designs is just under the bust, one of the most flattering fits on a woman. The skirt portion is aline or more open and flowing to accommodate a more able hip and leg if needed. Dresses are sleeveless, so arm fit is not an important consideration.
We recommend judging your fit based on the size of your upper body above your waist and what might be a comfortable sleeveless shirt size for you.
The interior bra has soft support and some give. If you are looking for a tighter fit or would like more support up top, consider going with a smaller size that still fits your bra size range.
If you have any questions about what size would be best for you, please email us at firstname.lastname@example.org and we'll make sure you have the perfect fit for you.
