Growing up in the 80s and 90s there’s so many that come to mind! But an iconic scene that sticks in my head is Ilan Mitchell-Smith wearing woman’s bikini panties and a crop top in Weird Science

It's the one I mention when people ask what movie has a memorable briefs scene. This is exactly what my high school locker room looked like. Majority was white briefs. Entire movie is on YouTube but I've saved at this scene for your enjoyment.
