Do you have any pictures? I can then give more constructive criticism.

But going on the assumption that,

a) Your density is correct
b) Your colour is correct
c) Your blend and style looks good

then....ignore the naysayers.

You are in your 20's, you want to look good. If you look good, you feel good, if you feel good, you do awesome!

Work on the inner game too, so if someone does find out...they can't make you ever feel inadequate. By this I mean, develop other sides of your personality, have some come back responses. Always have a a back up pieces, and make sure you're enjoying your 20's....they only come ONCE.
