Banana Republic is one of the most notable workwear staple stores of today. No doubt, their quality is very good and they offer appropriate trends for even the most conservative offices. As far as affordable goes though, it's one of those places where it's easy to spend over $100 on as little as two pieces.
I do like shopping there though, but I do it sparingly and smartly. Banana Republic offers 30 to 40 percent off their regular prices at least once a week. Sometimes, you can hunt for an item on sale with additional reduced prices.
If you happen to have a factory store in your nearby neighborhood, that would be the best place to stock up on BR gear. The dress below is from the BR factory store and it's one of my favorite pieces for summer. At $49, it works well within an affordable workwear budget. As with almost all my peices, I like them to be versatile. You could wear this with black tights in winter and even with a white blazer for a more summery look.
Today, select styles are on sale at Banana Republic. Happy shopping!
