Express makes a black jean in 00 long. It's the Stella and I just checked their website, and it's not in stock right now. The description says they low-rise, but they're really not. The Zelda on the other hand is very low, stay away from those. I'm in kind of the same predicament, I currently only have two pairs of jeans that fit me, sort of. I have the Stella one's from Express in black, they are a 0 regular. FYI, they don't sell 00 in the stores, online only. I don't even know where to turn for jeans. My 7 (seven?) jeans, which I paid a fortune for, swimming in them. My Joe's Jeans, same thing. I will pay anything for a good pair of jeans, I had over 40 pairs, now just two.
P.S. The last time I wax in Express, I saw a tall, beautiful skinny girl browsing around. I basically accosted her and asked her where she buys jeans. She said she gets hers from Buckle.com. She was about 4 inches taller than me and much skinnier. I almost asked her if she was a SG member, I just had a strong suspicion she was. It's been a while since I've laid eyes on someone so tall and skinny.
You're a superstar thank you!
