Prom dress advice?

Prom dress cuts?

Hi, graduating class of 2025 woohoo! I’ve been thinking about prom dresses lately and have never worn a full length gown. I found in semiformals I tend look better in bold jewel colours due to my skin colour, but am having trouble deciding on a cut that would look good on me. Usually it’s the cuts that are more of a problem for me because I am a petite gal with curves at around 140lbs. I also row so some of it is muscle but I can’t lie I will never refuse a sweet treat lol. Anyways, would anyone be able to suggest features I should be looking for in a prom dress that would flatter me? Things that have worked for me in the past for broad shoulders were v-neck, wrap, or halter necklines.
