Lord's Yukata (Blue), Drawers, and Clogs Rendered Useless

These items were obtained back in 1.0 through an event.
The problem is, I was a Male Hyur back when I obtained these event items, meaning that only a male gender character can equip these items.
Now that I've changed my name/race/gender for 2.0, these items are literally just sitting in my inventory unusable, wasting space.
I am unable to equip, sell, or discard these items.

Unless there is a way to exchange these items for their female counterparts, I would like a way to discard these items.
