The prom dress looks great on you, and it's perfect for the occasion. You look stunning in that red dress, so go ahead and wear it to the dance. If you feel like the fit could be better, especially considering your slender figure, you can always have it tailored to your measurements for a perfect fit. For future dances, you can explore different styles of dresses. Buying dresses online is also quite affordable now, and I often shop at Sonicemall.com. They offer factory prices with a wide range of styles to choose from.
