for me its new clothes. I recently went out and bought some nice new bras when my old ones got a bit loose. They weren't on sale or anything!
I am enjoying wearing my "skinny jeans" that I got last year before i put the weight back on, I have lost it again, this time for good!
I recently took 3 skirts that I really love for work into a tailor to be taken in so I can wear them again, they got a bit loose!
I hope by next summer I will be needing new ones completely!
