I'm not sure if I've failed or not. In the past week I've purchased:
2 pairs of running shoes. These are duplicates of the discontinued model I'm currently running in. Deeply discounted and delay the hassle of having to find a new shoe for another year.
A riding vest. Not on my list of items, but it's the perfect elegant riding vest, packable down, so I'll use it as a pillow and extra layer for the Peru trip, and doesn't add to my work wardrobe, which is really where the closet bloat is.
A North Face jacket. I gave in to perusing the clearance racks when I was in TJ Maxx looking for certain travel items yesterday. They had this one jacket in my size for 50% off retail price, and it fits me perfectly, is black with tasteful pinstriping, just the right articulation in the shoulders and elbows, and just the right length and cut for a winter riding jacket, in a material that won't collect hay. I left it in the store yesterday, but then I went back this morning to return the one little item I'd purchased, tried the jacket on again and bought it. I know I'll be happy about this when next winter rolls around (this one appears to be over).
Tempted fate by trying on a pair of designer jeans on clearance for $17.80 at Nordstrom Rack, but left them in the store.
