Dear Ladies, i need your advise! i got a Christine bag and everything is perfect except i feel the stap is too long. they can't tell me at hermes if it is possible to shorten the strap or not! today i asked a first-class shoemaker who would do it for me... would you let to do there or wait? if i do a strap-shortening somewhere else Hermes still going to recondition the bag for me???
