I did - I increased the front and back length by the same amount but that's not what I received.Did you alter the measurements of the front & back of jacket?
I used the same measurements for my previous custom jackets and they turned out fine, so not sure what happened with this one - hopefully just a one-off but you never know given the recent feedback..
As an aside, I would say the length inputs are a little confusing. The back length (called "jacket length") is a standard input whilst the front length is an "advanced" option. However, if you alter the back length, it doesn't automatically update the front length in the tool, which seems odd to me (if you only changed the back length and not the front length, that would surely create an uneven hem).
Maybe someone else can weigh in on that?
