A fitted prom dress with a high slit works because it suggests movement and shape and reads as more interesting than a straight fitted dress. The slit means you can actually move and sit and walk without the dress fighting you. High slits work best with fitted dresses because the fitted silhouette means the slit reads as a design choice rather than a necessity. We look for slits that are clean and finished well and positioned in places that make sense with how you will actually be moving. A slit in a fitted dress creates the illusion of a longer leg and adds visual interest without adding bulk or volume. A fitted prom dress with a slit is the piece that proves you can be both intentional and practical.
