Frequently Asked Questions (FAQs)

1. What is an appropriate length for a dress?

The ideal hemline length for most mature women will be short enough to highlight your calves, the prettiest part of your legs. That means the length will vary from the lower half of your knee to as much as 2 inches below your knee, or longer—depending on how full or narrow the skirt is.

2. Are formal dresses long?

Dresses for formals are typically long and have elegant detailing such as beading, embroidery, or flowing material. PromGirl has put together a large assortment of formal gowns that are fit for every formal event.

5. What do you wear over long formal dresses?
