Bc you are petite, you should be able to find tons of stuff at the cheapy mall teeny bopper stores...it is prom/wedding season after all.

Not suggesting a prom or wedding dress. Just saying, lots of girls and women need dresses, all kinds, this time of year.

I'm thinking something like a black or jewel tone loose (no waist, NOT form fitting) just-above-the-knee, knit tank dress w/ rhinestones. You see them all day long at Deb, FXXI, Maurice's, even H&M.
