opinion on prom dress

Hales
Hello ladies, for a girl who Is Insecure with her arms I am planning on trying to find a long sleeve dress although I have currently been working on losing weight by eating right doing yoga, and just hitting up the gym for a couple a minutes. I am some what lovin' this dress but, then again I can't decide If I'm just digging the color & the fact It's long sleeve please leave your opinion below with full honestly (of course please don't be rude)
