I think this topic can easily be considered unisex - do you have a favorite pair of jeans? More than one? Really? You are a lucky duck then.
I have a blue pair, a black pair, a used-to-be black pair, a tan pair and a brown pair that I can still wear even though they're speckled with bleach but if it's dark out - I'm good.
If you have a favorite pair, it doesn't necessarily mean that's the pair you look your best in. It means (at least for me) that's the pair I feel the most comfortable in.
Mine are the ones that used to be black and are now - well, I'm not sure what color you'd call them now. Gray? Yeah, gray. They feel like an old slipper.
They don't strangle my waist, the zipper is long enough, they are ABOVE my belly button. That part is crucial. Below the bell button is fine if you're 17 years old, 6 feet tall and weigh 112 pounds. Truly, those are the only people (men and women) who should be wearing those jeans. I don't mean to sound like the fashion police but, come on, you know I'm right.
My comfy jeans are at the end of their life. I need a new pair. I hate to shop for jeans. The struggle, the sweat, the swearing that goes on in those dressing rooms - it's sad.
I need to throw those poor, old, comfortable jeans away.
But not today.
