Why not take your belts to a shoe repair shop and have them shortened? Easy to do and only costs a few bucks. IMO that would
be easier to justify the emergency funds for.
Congrats by the way on the weight loss. I've been losing weight recently and know the frustration of nothing fitting well all of a sudden. I can't wait to stabilize in a couple months so I can replace/alter stuff.
Honestly, it never even occurred to me that I could do that. I have a black belt that is too big also (same as my brown one). I don't really need a black belt at this point (don't wear black shoes very often), so I'll take it to a place at the end of the month.
