I hate the store but they're the only one who seems to carry Bullhead Jeans, and I love them. So yeah...
Thrift store jeans, On sale half price
The underwear at Goodwill is nice
I am a big, big fan of the Levis 527 low rise boot cut jeans...got 7 pairs. What I did is finf my size, then ordered a bunch off eBay for like $20-30 a pair, which is a good deal as here in Calgary, they are $80 in retail stores. They are nicely fitted through the thigh (room, but not baggy) and they flair out about 1/2 an inch at the bottom compared to the knee. The crotch also doesn't go to my knees as I wear them a bit lower off the hips. Wash them the first time in vinegar, and it sets the color, and they last for years...best jeans ever.
