Well, I've been the same weight for a few years and had to buy all new clothes when I lost weight.

But, I can gain it back verrrrry easily if I'm not careful.

So, I have kept some of my bigger sized clothes, mostly skirts and a few slacks. I wear my huge baggy sweaters around the house becasue they're still in great shape.

Not to be a pessimist, but, if you're like me, you go on binges. I'd say keep a few so you're comfortable, but get out of them asap!
