I'm the biggest obsessive buyer here probably...I went to Claire's 3 times in 2 days because they had their 10/$5 sale and it included these necklaces and necklace sets that are more prom jewelry than anything, and originally priced up to $16.50. I work at Bath and Body Works and I buy stuff whenever I can, most recently I bought some suncare products that FINALLY went 50% off. I'm also obsessed with Victoria's Secret to the point where I go there EVERY paycheck (I never shopped there until I got my job at Bath and Body Works) so yes, underwear is something I can't stop buying. There's a store in the mall that sells these faux silk scarves for $3 a pop and I have probably a dozen of them, in addition to the 25 or so winter scarves I have made. Makeup is a big one, but I've refined my tastes-it's not about buying tons of Bonne Bell or what not on clearance, it's about buying a couple makeup counter pieces so I qualify for the all-important GWP where I get...more makeup.
Oh yeah, and don't forget the polo shirts. I probably have 15 to 20 of them.
