Peace,
Well, I think it's up to everyone to choose what to wear on the beach.
If I really want to melt into the crowd of people on the beach I should wear a normal bikini or swimsuit that most women wear. If I wear strange clothes people will notice me more and I get attention that I don't want to get.
A suggestion is to wear bikini when you lay down to take sunburn and when you take a dip into the ocean but when you will take a longer walk along the beach and perhaps buy an ice-cream then you can put on a beach dress or something.
