Tall thin woman - what brand?

Hi!
I'm a newly graduated, newly licensed RN, and I'm looking for some help in expanding my collection of scrubs (currently: 2 pairs). I'm 6' tall, I weigh 150#, and I usually wear a size 7/8 pant. I buy jeans with a 34" inseam. I have a little bit of a butt, but not much. I've been to one of the local scrub stores, and there's only one brand there that looks remotely OK on me - Cherokee tall flare pants look OK, but the hems of the flared part drag on the ground a little (even though they claim the inseam is only 33.5"). Plus, I have mediums, and I have to retie the drawstring about 30 times a day or they start to slip off. I've never been a small in my life, maybe all their sizes just run really big? I'm looking for functional more than fashionable, so I need pockets, but I also don't want to look like total crap. I wound up wearing men's pants in school, since I never did find tall pants in white at the local stores (too many students having to buy them, I think). I'd love suggestions for brand ideas! Thanks all!
