ELI5: Explain Like I'm 5

Vest

A vest is like a piece of clothing that you wear over your shirt. It's like a shirt without sleeves and usually doesn't have any buttons or a zipper to close it. It's just like a jacket but without sleeves. You can wear a vest to keep yourself warm or just because it looks fashionable. Some vests also have pockets that you can use to store things like your phone or snacks. You can wear a vest with lots of different outfits, like over a t-shirt or dress shirt, and it can make you look very grown-up and stylish.
