Thank you, I texted my SA and he told me that going to my local Hermes would be easiest if I wanted to return or exchange. I ended up exchanging for half a size up which fits perfectly. I also didn't have to pay the difference in sales tax incase anyone is wondering about that. I was pleasantly surprised since I was expecting to and it would have been an extra $30~$40.I would return, as well. That way you’ll get the full credit to buy what you like. If your intent is to maintain a relationship, tell your SA and let them know your situation. They will let you know the best option.
Good luck!
