This annoying guy I know was saying that bikini style panties were granny panties. and that boyshorts and cheekies are tolerable, but that thongs are the only style girls over 15 should wear and my friends agreed with him.
I don't understand how boyshorts and cheekies are tolerable and bikinis are granny panties. Bikinis are made of less fabric than boyshorts and cheekies.
I think those are hot looking. Granny panties are more like this: link
These are ugly, and scary. Bikini style are close to them, but very cute to see. Thongs and G-strings are hot. Boyshorts are okay. But wear what you want to. It's all on how you feel in them, and how you like them.
