God, I live in jeans. I don't really know what I would do if I couldn't wear jeans. I definitely have some favorite pairs. For me, its all about finding a skinny fit with great cuts, washes, and details. I'm a small guy, so most of the "popular" designer-y jeans don't fit me, so I have to go for women's. Which is actually fine, cause you girls have WAY more choices when it comes to denim.
Anyhow just a little list of my favorites:
-Dark Blue Ruehl no.925, Jane Bootcut: One of my favorite everyday jeans. Nothing distracting, just simple, great cut, amazingly skinny, and look good with everything!
-Black Habituals, Skinny: These things are great for night or day. Black denim, with this diagonal cut and seam through the knee with a little zipper detail at the bottom hem.
-Light Antik Denim, Western Cut: I love to wear these when I go out. Throw on some cowboy boots and a big sweater. The detail in these jeans is sick, I love them, worth every penny!
-Dark True Religion, Joey: One of the my classic pairs. I love these and probably couldn't live without them.
-Black Seven For All Mankind, Dojo Cut: These are a great take on dressy denim for me. They're tight in the thigh, but have such a great trouser cut at the bottom!
