It seems some modders have uploaded a version of Bodyshop that's compatible with the Legacy Collection (available, among others, via Mod The Sims). I wonder why EA didn't include it, it would make so much sense. I was trying to do the Not So Berry challenge as adapted for Sims 2 (found it on Tumblr, I think) but had a hard time creating the first Sim since mint isn't a colour you encounter often in the game. Even the option of changing the Sim via a mirror doesn't give you more options, and the only vaguely mint-coloured haircut is terrible. I haven't downloaded and installed Bodyshop yet because I decided to ditch the challenge after a while and instead just play freestyle.
