I bought all the red shirts to get the forum title "is a red shirt" but I don't actually like two of the shirts. Can I sell the ones I don't like and keep my achievement and forum title or will I lose it?

You are more than welcome to get rid of any piece of clothing you want after you get an achievement. Nothing gets taken away from you!

yay that was what I was hoping to hear, thank you! And once again your avatar is flippin' insane, I love it.

Thank you!!! I don't get to use this wig often but I love it.
