Should I wear the bikini or the other one?

so tom. Im going with my friends to the swimming pool! Since we are muslims we are going to the ladies day!! But actually the pool isnt like covered with a surface so I said im gonna wear my bikini but then I figured out it wasnt covered and my bikini was cut from the side but it's actually not obvious!! So I said Im gonna wear my other suit which is like half sleeve and like it's pants are kinda long soo I guess it looks better but like all my friends are gonna be wearing bikins so idk!! And my parents ofcourse arent gonna choose the bikini sooo idk!!! and I dont think the long one looks good cause it has this thing on my chest so it makes my boobs look really big!! but my parents say it really looks soo good on mee sooo wt do u think??

Bikini

If you're under 18 and still living with your parents, do what won't cause a problem in your house. When you're older and on your own, you can do as you wish. For now, choose your battles with your parents wisely.
