Does this dress look okay?

Hi, I've been looking for a prom dress to wear in a couple of months and I found this one. I think it's a really pretty dress and I like that it covers me up but I've got really bad self confidence issues and I feel really anxious about wearing this in front of others. I think it makes me look fat... What do you guys think? Should I look for another one or just give up and not go? Thanks in advance!💗💗 (Excuse the bra straps and the shoes, I won't be wearing those lmao😂) xx
