We're very lucky -- I don't need work clothes, and the most dressed up DH ever gets for work is khakis and a golf shirt. Our budget used to be $100/mos for the both of us, but after DH's company-wide paycut, we lowered it to $60/mos. DH almost never spends any of his, where I tend to drift over my half, which then gets taken out of my allowance. Our biggest problem is that we both lost about 20 lbs each and, for instance, all my pants keep trying to inch doooooown (and with that stupid 1% of elastic they put in everything, they already did that even when they were the right size!). But I'm still not of a size that can find clothes easily at thrift stores. So the budget has taken a little bit of a hit in the clothing dept, but not too much.
Though I have to brag that my best score this year was on a pair of sandals at Kohls -- took them to the front, the UPC code wasn't recognized, she called the manager who found out that those were the last remaining pair from last year's stock. So I got them for $1.50! The little lady next to me in line said, "Did I hear that right?! Did she just get those shoes for $1.50?!" Isn't the best deal the one you weren't even expecting?
