I don't want to advertise for a certain store but we have a few stores locally that specialize in name brand 'seconds'. I buy a lot of clothes there. I just check them over for zippers that don't work or stains. They are new clothes. I usually pay 7-10 for business casual pants and about 10 for jeans there.
It is hard to part with those bigger clothes. I did it about 3-4 months ago. I gave away 2 33gallon trash bags. The sad thing is that since then I have pants in size 24 and am now wearing a 20. So in a month or so I won't even be able to wear those 24's as sloppy pants anymore. There is always that fear in the back of your mind that one day after a binge you are going to wake up and not fit your newer clothes anymore.
