ELI5: Explain Like I'm 5

Skin-tight garment

A skin-tight garment is like wearing a super tight outfit that hugs your body really close. It's kind of like wearing a second skin. You might wear something like this if you're an athlete because it can help your muscles work better and keep you from getting hurt. Or you might wear it just because you like how it looks! It's kind of like wearing a really tight sock, only it's all over your body!
