AIO for demanding to be paid after wearing something inappropriate to babysit

hi! i am 15 and have been babysitting this family for over a year. they are more on the conservative side, and a lot more religious than my family, but they are generally nice and i love their kids. i did not receive payment from them the last time i babysat, and so i reached out and they are now saying they will not pay me the full price because i was wearing something inappropriate. just wondering if i am overreactingreacting

for context, i was wearing a sweatshirt over my tanktop (3rd pic) and only took it off after the kids asked me to run around with them.

i babysat from 4 to 10:30, and normally charge 15 dollars w a 5 dollar increase per kid, so 20 dollars for 2 kids.
