Here are some style tips for thin guys, or those that are too tall that they look skinny.
1. Learn the art of layering.
This can give you volume. It's easy to do this during cold days because you have every reason to, but it can be challenging during hotter days.
2. Never wear loose t-shirts and loose pants. But don't wear "too" skinny jeans, either.
First and foremost, loose pants and t-shirts are so 1990's. Second, you'll only look like a walking hanger.
3. Always buy a shirt whose length covers only up to half of your pants' zipper.
If it extends past your zipper, try another one.
4. Buy pants that don't give you hips.
There are pants that are a little loose in the thigh area giving it a "balloon" effect.
5. As for shoes, choose sneakers that's not bulky and one whose top line is below the ankle.
Bulky shoes make you look funny.
