I'd say take a trip to the closest (bigger) city and check at
smartpages.com (Yellow Pages online) for consignment or resale shops. I'm cheap and I refuse to buy clothes that I'm trying not to wear (i.e. bigger sizes)

Also take a good inventory of your closet and see what's MISSING. Like you've got five blue blouses and no blue pants, then one pair of pants can make a big difference.

Also - I'd know if you're inclined but if you sew or can borrow a machine. There's lots of really easy skirts that are elastic waistband that you could make for really cheap. You could probably make 2 or 3 in an afternoon.

Best of luck,

P.S. If you've got an Avenue clothing store - I'll send you some coupons I got in their catalog but they have to be used in the store.
