Hot Topic sells jeans under the brand Social Collision for guys, and they are great jeans. They have a large variety of colors with different fits based on how skinny you want them to be. Most of the jeans have some percentage of spandex in them giving them some stretch. I have never worn more comfortable jeans, they feel almost like sweat pants.
The prices are also amazing, regularly they are about $29.00, but Hot Topic almost always has a promotional going on, plus you can often find coupon codes online for online purchases, so they usually only cost about $20, I got my last two pairs for $14 each.
There is one downside to these jeans. They are not durable in the least, I have owned a total of 6 pairs of these jeans in my life, two of which generated rips down the seam in the crotch, and one of which the button ripped out. Re-sewing them is a mild pain with normal thread as the fabric is stretchy and the thread is not, but I was able to fix them up. I am sure if you found some thread with stretch in them they would be good as new. Even with the fallbacks I have experienced with these jeans I do not plan on buying any jeans but them for a while.
