>>18496035 (OP)Like with most things, if it's the outline of a hot guy, awesome, if it's the outline of an ugly guy, repulsive. Similarly to women and cleavage. Everyone wants to look at the cleavage of a young woman with perky tits, one who weighs around 120 pounds or so but happens to have large tits in proportion to her size; but almost no one wants to look at the cleavage of a 300 pound 80 year old woman with saggy ass tits.
I wouldn't go around purposefully showing your outline though. That'd be kind of douchey. Especially if it's an area where a lot of kids are around. If the type of pants show an outline by default due to the material or fit or whatever, cool. But purposefully dressing to show off the outline comes off as trying too hard. And same applies to women and cleavage, really. If an outfit shows a small amount of cleavage by default, cool. But purposefully dressing to show as much cleavage as possible, trying too hard.
