I only wear g-strings. They go with anything, they're so light they feel like your not wearing anything, their very feminine and girly and they look as sexy on as they do off.
I like boy shorts
thongs are good for when you are wearing tight pants and you don't want people to see your underwear line. But I hate when I first put it on because it feels like a constant weggie but you get use to it after awhile
bikini is comfortable
i like underwear with pretty designs on it and are comfortable
