Recycling!
I love Maxis boardshorts, but they have only been available for adult males. I remade them to fit grandpa and grandson. It's not as easy as you could wish, as elder, adults and kids have different body types, so you have to tailor the clothing.
Some of the boardshorts were previously made available for grandpa by moonlitmaiden, but they were just recategorized, so they change grandpa's body form into adult form, which I'm not so fond of. Grandpa has to look like grandpa! Also, her swimtrunks require Bon Voyage expansion, and mine will work with base game only.
