The key to looking sexy without being slutty is to only draw attention to one part of you at a time, instead of all at once.
One day, show off your t*ts by wearing a tight or low-neckline shirt, but keep your legs covered with modest pants that aren't too tight.
Another day, show of your legs by wearing a short skirt or shorts but wear a non-cleavage-bearing shirt.
When putting on makeup, don't throw on a ton of lipstick, eyeliner, and blush all at once.
Instead try putting on a lot of eyeliner but no lipstick or foundation one day. Then another day do lipstick with nothing else.
Maybe one day dress very plainly but do something really elegant with your hair.
Being respectably sexy means having one part of you sexed up at a time while the rest is still classy.
