originally drawn march 2024 for april fool's :]

for a little context, this is from my take on Underswap (named Underswap MH) which doesn't fully swap the cast's personalities or leave personalities unswapped, and goes for a sort of middleground! this is just the bros swapping outfits for The Funny Day though

(quick note that my Swap Papyrus always wears various mismatched socks which Sans is imitating, but the bi flag sock he's wearing is his own; I headcanon Sans as demi-biromantic and Papyrus as aro)

also the tumblr post has an extra doodle with Alphys and Undyne's less successful outfit swap ✨
