When I saw the datamined image I didn’t see the red section, I thought it was like the modified image and bought it as soon as it was available without even checking.
As a woman who wants to look good (at least in game lol) it actually really got my back up when I thought that the dress had been lengthened.
Part of the reason I thought it had been lengthened was remembering what happened to the original Redguard female shirt. That used to be my favourite top and...anyway, not to turn this into a complaint post, I have the current version of the dress and I would buy the shorter version.
At least do it for the max body mass Orsmer.
