Speak of flagship locations...
If you are #blessed enough to live near an RTR location, your rental life will be a legit walk in the park. Instead of sending back your items in the mail, and waiting until they've been received and processed, you can scan in your items at the store and have a new rental spot open up immediately.
There's also the opportunity to have your order shipped directly to the store. This saves about a day in wait time on each end, and also allows you to try on your pieces in-store, so if you don’t love something you can scan it back right away!
Finally, if you find yourself in a pinch, you can always just use the RTR stores as your personal closet. The selection is limited, but it's a lifesaver if you find yourself with a last minute event (the flagships always have fancy clothes) or if you're flying out for vacation the next day and you don’t like something you ordered for your trip.
