Not cute. Sometimes a little sexy, but just not all that good looking. Was with a girl yesterday who wore red panties with white polka dots -- somehow it just looked cuter tahn any thong I have ever seen.
I think generally it will be considered sexy more than cute.
Cute has this innocent connotation to it, and thongs are more sexually appealing.

A guy that I like loves them (I hate them) and few other guys that I knew just think they are gross or trashy. I myself think it depends on the ass, because I knew this girl that was about 300 pounds and she would wear them in the locker room constantly. All I could think is, "I don't want to see the moon so early in the morning" lol. She turned me off of thongs ungracefully, but at least she had confidence ... I guess.
