Hi all, I just purchased a size 37 Tweed espadrilles which fits quite snug when trying at store. I have also tried the 38 which was way too loose, so I decided to go with 37. But when I tried again at home, it was super duper tight, may I know how much would it stretch out for the Tweed espadrilles? this is my first espadrilles, should I return it? Thank you in advance!!
