I'll answer for the queer boys only :3.

When they're home and don't need to be modest:
Eddy, Pat, Skizzy - Nude
Darrell, Trent, Chester - Undies only (the locker room scene should clue you in on what they choose to wear 👀)
Corey - Tank top + undies
Dave, Cliff - T-Shirt + Undies (Cliff wears a crop-top sometimes u.u)

When they must have some modesty:
Pat - Undies and a shirt if you're lucky (you'll have a hard time making him wear anything more)
Darrell, Chester, Corey - Tank top + loose-fitting shorts
Cliff, Dave, Skizzy, Eddy - T-shirt + pyjama pants
Trent - Button-down, long-sleeve pyjama top + matching pyjama pants (he needs button-down b/c antlers 🦌)
