I noticed the prices on some vanity gear is way more expensive for the female version vs the male version of the same gear.

For example on my server Sargatanas
Female - Coronal Summer Halter is 1,600,000 gil
Male - Ti Leaf Lei - 80,000 gil

Its the same piece of vanity gear except the female version is 20x more expensive vs the male version. Almost every piece of vanity gear that has a male and a female version the female version is always way more expensive.

Can't something be done like having 1 item if it is sellable so the gender of your character doesn't change the price. The only reason vanity gear is so much more expensive is because more people with like to dress up their female characters vs their male ones.
