Have a holiday booked with my gf coming up, and the holiday shopping has us excited. My gf only has one bikini at the moment however, and said she wants at least a swim outfit for every other day. She asked me if she could just wear some of her normal underwear/panties and either get bikini tops to go with them or some tops she already has. Her explanation was that some of the panties she has are waterproof/not absorbent, similar to normal bikini material, and she already likes how they look so it would save her the hassle trying to find things she likes, and they would be similar to the bikinis she would get anyway. I usually wouldn't be worried about something like this, but the ones she shown for example and most of the others are a lot 'cheekier' and also less coverage underneath then the bikini she has, and even that is pretty showy. Also, I'm not sure if she remembers but a while ago she discussed with me one night that she had been turned on before thinking about showing herself off, particularly for perverted older men. It was probably a spur of the moment thing she's now forgot, but I can't forget it and am worried that she is already aware of the attention she will get and just doesn't mind it.
