Well most guys like you if you look comfortable in your own skin. I wear skinny jeans and and high tops (any color) and a tee.
It means he doesn't find you attractive.
He finds you attractive.
Where a tight shirt to start
It means he thinks your attractive so he is trying to look better when he is in your presence.
That depends on the guy...
Without seeing a picture it is hard to say if a guy is attractive. Whether or not a man is attractive is a matter of personal opinion, what one person finds attractive another may not.
If a person is referred to as eye-candy, it means that they are an attractive person, and enjoyable to look at.
I think blue and brown look awesome on guys, those are attractive colors. I have both, my eyes look mesmerizing when I wear them.
Guys don't want to have boobs of their own. They want to look at and play with your boobs because they are attractive... maybe.
If a guy gives you a second look, it typically indicates that he finds you attractive or interesting in some way. It could mean that he is intrigued and wants to get to know you better.
Maybe he finds you attractive and doesn't know how to talk to you. Start looking back at him.
Because he may find you attractive. Also as humans we have tendencies to want what we don't have especially if there is potential in that something.
