I adore my Panache sports bra - pricey but worth it to keep my 34DDDs still. See if these sites will ship to you - her room, bare necessities, fig leaves. I got one pretty reasonably ($50 instead of $70) by not being picky about color.
Ditto with sneakers - I view good sneaks as pain prevention. I got fitted at a running store, but if you don't have one, try this -
www.roadrunnersports.com/shoedog - it asks questions to guide you to the type of shoe to try.
Ad I hate being sticky sweaty, so I love wicking fabric. Most of mine is from TJ Max or Marshall's, so not breaking the bank. My splurge wicking tshirt was on sale at LL Bean.
