Congratulations Jen!! That is a beautiful bag!
As far as caring for it... The suede will be the most difficult part to keep clean. Thankfully, it's a dark color, so you're somewhat in luck
. You won't be able to prevent it from getting dirty, but what you may want to do is pick up some leather/suede protectant that will at least keep it from getting water damage should you get caught in the rain
. Check out stores like Foot Locker, City Sports, Clark's, Berk's, or any other sporting/outdoor/leather goods store for the spray. Coach makes a leather cleaner, but nothing to clean suede that I'm aware of.
As far as the jacquard (signature fabric) goes, if you get a stain, a little soap and warm water should help. You can also bring it into a Coach store and they will clean it for you (they may have to send it out, so you'll be without it for a few weeks). Do not use Shout Wipes or any of those other detergent spot cleaners/treaters because you will risk bleaching/staining/discoloring your bag.
Oh, and keep the hangtag on!
You don't have to take it off, but if you want, it also makes a cute keychain/keyfob.
