I am so sorry to hear that and mine was close enough thankfully not to be a problem. I didn’t customize the color and chose rouge h from her options but did customize the strap(125cm) which she accommodated.
I also asked h and told they don’t make custom straps for herbags. Unfortunately I have quite broad and find the h straps getting smaller- i really wish they would offer more custom options in the normal leathers.
So after using the strap last week in paris i found out the hard way the leather wasn’t properly sealed and i got res color transfer on my light color clothes. I also learnt h will never make a herbag strap longer bc “it ruins how the designer envisioned it” but did chat with service desk about a longer halzan strap. They took my request and will email me back in the next couple of weeks.
