I declare that ...

... having to buy new lingerie because of weight reduction is fantastic.
so the other day I went out for a walk in baggy jogger bottoms as it was very hot out. After a few minutes my panties were slipping down fast, I readjusted and carried on but had to return home. I pulled out a brand new, unworn pair that were fine until I started moving about.
I then got to spend a happy couple of hours buying new items TWO sizes smaller than the ones I had.
I think wearing shorts and light yoga bottoms had kept my knickers in place but any excuse will do.
