No.mermaid prom dress won't make you look shorter.
It's really a good idea to dress-up like a mermaid. There are a lot of other sexy and hot dresses around too.
Would a mermaid prom dress make me look shorter?
You have not mentioned what's your height so we cannot actually answer your question. Please mention your height, also whether you are fat or slim...
Yeah i think you will look amazing!
word of advice though, dont wear underwear lol
if you wear regular underwear you will be able to see the lines and if
you wear a thong, it will make you look like you have love handles.
