Honestly... I would call and ask for a Handbag SA. If you don't have a specific SA that you already work with there... I'm not sure what kind of timely response you would get. I suggest giving them a call BEFORE about 3pm or 4pm, otherwise they will be too busy, mornings are the best time to call.
BalNY's return policy is VERY strict. You only have 10 days to exchange for a different bag, and you cannot return for any reason. I've heard you only allowed 2 exchanges in a lifetime, so basically I would consider their policy a "No return" policy.
If you are on the fence about something or not sure if you are going to keep it, I would suggest going through someplace like NM or Saks, where you can actually return or exchange without it being a big deal. Good luck!
