15-20 pairs?? I think I own 2 or 3.
I own about 10 pairs of jeans - granted some are "around the house" jeans, and some are very nice looking. I wear jeans all the time but know when not to.
There a hundreds of different kind of jeans, classic fit, easy fit, stretch, non-stretch, low rise, ultra low rise (these are the jeans young girls wear when they should not), boot cut, flare, straight leg. It is exhausting!
My personal favorite, just below the waist, boot cut in Long!
