wigs??

I had to cut ALOT of my hair off from damaging it with bleach. I have barely even shoulder length hair and my face is kinda round. It makes me feel un-sexy and I feel self conscious about it. I want to get a wig until my hair grows out a little more because of this. I know tons of celebrities do it but I'm also a little worried about people making fun of me because they will know it's a wig. Do any of you guys wear wigs? What is the best place to order them online?
