Buy your guy a suit. I swear a guy in suit is so hot and makes me want to drool. If you’re the one choosing and buying the suit, he’ll feel obligated to wear it on special occasions and you will know that he’ll look good in it because you chose it! If you can’t afford a nice suit (because they can get pricy) just get him a nice tie or cufflinks if he already has a suit. It’s something a guy should have in his closet, and if it’s from his girlfriend, even better!
