How do girls seemingly change their boob or butt size?

[104755555]

many girls i know i will often see them have bigger boobs or butts some days, and smaller others. do boobs and butts shrink like penises? I swear they dont seem to be the same by day. This one girl i went on a date with the first day i met her, her boobs were huge then the next day i met her they were almost gone i hugged her and there was no way her boobs were that size the day i met her she's bueatiful but that was a serious bummer?

It's called a push up bra or padded , as for their butt that could be the type of underwear they wear or even high heeled shoes will enhance it

Clothes can have a big effect - Tight pants can give an illusion of a bigger butt and a push up bra can give illusion of a bigger chest.

maybe its what they wear that makes it look so different from day to day.
