No one will give a shit other than yourself. If you want it, get it. If you want to wear it, get it. If you like it, get it.
If you're going to be too self-conscious and feel weird wearing a "girly" shirt, don't get it. If you feel like it's a bad thing to wear something "girly" don't get it because you'll look at it every morning and decide not to wear it purely because you're scared of what other people think. :v
