can't wear a white bikini?

It might be because white can be see through when wet. Unfortunately even bikinis. Maybe try to ask them if that’s why and then if that why get a bikini that won’t be see through when wet?

That's not a game.............

Maybe save up money or tell them that you can put padding in your bikini top, maybe that will help.

neither can I.  My back hair gets tangled-up in the snap !!!!

Wanted to add that white shows "Camel Toe" much better than darker colors. That's not a dirty word? :(

might be because they think it will be see through.

White is always going to be see through and many parents don't ever want their daughters to ever wear white until marriage including shoes. 

Make a deal with your parents 

Also ask why they say no to a white bikini.

   We wouldn’t know why your parents would think it.

They probably just don’t want you to wear one,

   It’s not the end of the world if you get one and besides you should social distancing  

Tell them you shave it all real well and your boyfriend likes it that way. 

White is see-through when wet
