as for the clothes aspect - say "hey lets go shopping" and guide him towards the mens stores - and pic up things you think will suit him :)
I haven't met a man who thinks it's a great idea going shopping on the third date. Most men hate shopping malls, and he certainly is not really into that. Also, I don't want to seem to bossy by suggesting a new wardrobe. He may think I 'm one of those who want to change him right away, and men don't like that. Shelley you and me are women that's why, going shopping might seem the solution, but from a man point's of view....(specially at the beginning of the relationship) . Also it's not the right time to start buying things for him like clothing.
Buy him some nice smelly stuff, thats about the biggest hint you can give
Then again it's not the right time to buy a perfume , and actually that won't solve the problem, I don't want him to be covered by perfume, I want him to shower everyday!!!
How can I tell him guys? I really like him but.... remember we been out for only 2 or 3 times.
