Michael and I both had some jeans that were too big, so I tried washing them in extra hot and drying them in extra hot. Guess what - it worked! They were the perfect size! They used to be one size too big, and now they fit perfectly. I'll probably have to always wash them like this to maintain that size, but it's worth it to me to not have to buy new jeans. :)
I haven't tried this trick with tops yet, but I'm sure it's trickier since the risk of them riding up in the waist is higher. Anyway, give it a try if you have big pants! What have you got to lose? You're probably not wearing them anyway.
HAPPY VALENTINE'S DAY!!! <3
