Basics:
Qwertee.com, Target! Kohls, Old Navy, TJ Maxx. Tautmun.com has some really nice basics that are dressy but not expensive. Maxi skirts from Target are great, love their basic tees and cardigans too. PJ pants and stuff from Old Navy.
Work/professional stuff:
Express, I have a bunch of their pants from back when I was working in an office and I still love them. Tops I would get from H&M or Charlotte Russe because they're cheap and dressy and since office work wasn't hard on them they would hold up ok. Blazers from Express or The Limited.
Dresses from F21, or Hellomollyfashion.com or from eShakti.com. Kind of expensive... but you get to customize the dress WRT your height, the length of the dress, the neckline etc.
Jeans:
Nordstrom or Nordstrom Rack. Can find really nice jeans at the Rack for way cheap(er) than usual, stuff like Lucky, Hudson, True Religion, Rag & Bone. I quit buying cheap jeans because they're my daily outfit right now and anything from Target, Gap, Old Navy etc would pretty much lose shape after a couple of wears and frustrate the hell out of me.
Gym/run/tri stuff:
Uh... everywhere. Dick's/Sports Authority for Nike and UA and anything that I wear golfing. Lululemon because, yeah. I know not everyone loves/agrees with them or their prices, but I have gear from when I was in 9th grade ( and I'm now 30 ) that is still in pretty much perfect condition, and I'm super hard on my gym stuff. Zella from Nordstrom. Athleta by Gap. Freddy, and AloYoga.
Bunch of small online indie shops like Livesore, Nobull, JekyllHYDE, Iron and Ink. One piece lap swimming suit from Dick's as well, was cheapish and hasn't been destroyed by chlorine in 2 years. Tri stuff from The Clymb (it's like one of those Hautelook type things but for outdoors/running/active/triathlon and usually has really nice deals).
Outdoor stuff:
North Face has an outlet nearby and I usually get most of my stuff from there. Snowboard stuff usually comes from BC Surf & Sport (none this year because I dislocated my shoulder in September for the 4th time and I'm not allowed to go boarding until I have a second surgery on it so I can't vouch for whether they had anything good this season). REI sometimes, it's a little pricey and plain for me. I find that Dick's and Sports Authority have pretty nice winter stuff in a range of prices too.
Shoes:
DSW 90% of the time, I love looking through their clearance stuff - last pair of gym shoes were a really nice pair of Asics and wound up costing $24. I buy my running shoes from Newton. Not cheap but I'm a mid/forefoot runner and they've been the best fit by far. Zappos for nicer shoes if I've tried it on in real life somewhere. Flippies and stuff from Kohls and Target. Boots from Nordstrom and Steve Madden, though RD bought me a pair of Frye boots after a particularly tough semester as a treat and I will probably never want to or need to buy another pair of boots from anywhere in my life.
Socks & undies:
Normal gym socks mostly from Target and Kohls, fun socks and knee highs/boot socks from sockdreams.com. Undies from Target usually, sometimes VS when they do a 5/$25 kinda thing. Macy's does a huge intimates sale once a year and you can get a ton of stuff for between $2 and $10 for undies and bras so I'll stock up then. My favorite bathing suit is actually from Target. Best fitting thing in the world and has held up to substantial use with only a little fading.
Sorry seems like a lot but if people are looking for new places to check out I figured I'd try and give as many as I could.
