People will probably yell at me for this but... Capes!

Lightning had one here just a few days ago, we should be able to too. Doesn't have to be any more fancy than hers either. At least after DX11 is supported.

Capes are the go to fashion accessory for lords, princesses, warriors, wanderers, mysterious strangers, etc. How can not even one single adventurer (whatever their style or purpose) have ever picked up a sheet or curtain and wrapped it around themselves to fell foes or swoon the opposite (or same, it's all love) gender? Come ooon, capes have been a long time missing in this game; from the first trailer of 1.0 they've been hinted at but not actually given.

The simple article of clothing allows for drastically different appearances and allows for different stats as well.

Capes! Get one at a Yoshi-P near you today~
