There's nothing wrong with what you're doing, and any girl who tells you otherwise is just jealous of the methods you are using, because they either don't have the guts OR the body to do what you do.
Just be careful not to go overboard, though. I personally think the main thing that makes a girl look slutty is her make up. Especially when they paint their eyelids. Ugh, it's horrible. =.= Same with fake eyelashes. It just looks weird and puts me off a little.
If you think you're not abusing the make up, though (or aren't using it at all), then don't worry. But if I were you I'd try keeping your bra and stuff out of sight (if you don't already). I don't know how you dress so I'm just giving you an idea of what might be considered too much.
And keep in mind that, depending on where you are, people will look down on you if you're showing off too much skin. It's not a very good idea to walk into a fancy restaurant wearing ridiculously tiny shorts and a tank top, for example. :I
But hey, I like your approach. It IS a good way to meet guys, and I wish more girls would come to terms with this and stop acting as though showing a bit of their body is a bad thing. Just because girls show some skin doesn't mean a guy won't be interested in her personality (as long as she actually have one, of course).
Depends of what your objective is. If you want to catch a prospective permanent boy friend, perhaps you should drop the slutty outfits. If, however, you are trying to have short term boy friends or one (or few) night stands, go and be slutty as much as you like and dare.
Mind you, being a slut might catch you a permanent boyfriend with the right frame of mind.
Honestly, it will turn a lot of other girls away from you, but that doesn't matter as much since it's guy who you want to attract. I would definitely be concerned about the guys that approached me, thinking they're just looking for one thing or that they're shallow and would leave me if I gained any weight. If that's not the case for you, then good for you! But in general, the good, long-term relationships may not come out of using this method :)
wear what you like,it's not wrong,but it is kind of pathetic to use it to lure guys in,most guys who you lure in will be the type that wants sex and only sex-unless you want sex too,if that's the case dress as slutty as you want
