How about a wardrobe achievement for having all different sorts of glasses/sunglasses in your wardrobe? Call it the "Four Eyes" achievement or some such. That'd be fun! Or an achievement for having different sorts of wigs in your wardrobe?
Suggest some others!
If there's already a topic like this, I apologize!
The glasses would be great for an Achievement, but for the wigs... UGH xD I could totally imagine that you'd need all wigs for an Achievement, but there are SO many and one that only exists 7 times on the whole site, so if something like this comes I really hope we don't need ALL of them XD
