Ann Taylor or the Loft.

Sign up for Banana Republic's emails. Almost every day they send a 30-40% off email online. This discount would put just about any of their items under $75. Shipping is free over $50 so you can order a bunch of sizes to try and return what you don't want (or return it to the store). And they have petites.

J. Crew has petites, too, but is pricier.

I need new clothes. I'm 5 ft tall and probably a size 8. Casual office. Don't want to spend $75 for a pair of pants. Where should I shop? Haven't overhauled wardrobe in many years and it's time. MoCo.
