Kmart & target are for clothes to workout in, clean the bathroom, hang out around the house, etc. You won't generally find their clothses to be great fitting unless you are built like a mannequin.
Check out Kohls, Marshalls, TJ Maxx for bargains. Dress Barn offers lots of basic separates - many of the pants have elastic waists without looking like they do - and they have petities. If you're still losing weight you don't want to spend a lot of money - you want some standards - black pants, black tank shirts for underneath, colorful top shirts / sweaters / jackets. that way the top and bottom of the same dark color (black, brown, dark blue) and a sweater/jacket or shirt over it you'll draw a straight line from collarbone to ankel which will be slimming - but you'll add color with the top.
It's a good idea to pick a color and add everything around those colors - you'll have more options. Black pants, skirt, tanks, shoes then colorful jackets/sweaters, scarves, jewelry, wraps to interchange. As you lose weight you can gradulally buy new black pants to wear with the same accessories. It'll look like you have a lot more clothes.
Only go to Department stores if you have coupons or if they are having sales. Most of the time you can get good accessories anywhere. Go early in the day when you're not tired, frustrated, hungry, etc.
I don't know about outlet stores by you - but I started wearing NYDJ pants (Not Your Daughters Jeans) - they're very expensive - but there's an outlet store not too far from me and I buy all my jeans there. I've gotten a lot of compliments on them and I spend between $20 - $45 depending on the sale and what they have in the store. They fit wonderfully and I don't feel like I'm squeezed into the waist.
Congrats on the weight loss! You go girl!
