Gaining

Need advice on clothes

Everyone hates WalMart, but they have larger sizes at a good price. If you gain much more than what you plan, jeans will not really work (except stretch ones which really aren't jeans) because your body will be a different shape between sitting and standing.

As far as bras, try a 34DD or a 36D. These are a lot cheaper and easier to find. Don't laugh at me or tell me it won't work before you try it. The cups would be the same size, but the band is bigger. But with stretch bras, you won't know the difference between 32, 34, or 36 because it will just stretch less.

When you go up a band size, you need to go down a cup size. Of course, assuming that you haven't gained. If you don't, the bra will be too big.
