One of the problems I find with it the cosmetic departments of SK is that there's just so many recolors, reskins, and accessories in general. I think I've came up with a better, and more user friendly, way of handling these items.

Recolor Tickets
We could give Bechamel an additional purpose, handling recolors. Instead of those items released as promo recolors being a separate item, why not make them a "recolor ticket." Recolor Tickets work like this, say you have an Angelic Raiment, You buy a Katastrophe Prize Boxes and get a Shadow Raiment Ticket. You take the ticket to Bechamel and he charges 5k crowns to change your Angelic Raiment into a Shadow Raiment. The Ticket disappears, but it stays in your permanent archive, so you could go back to Bechamel and change it again. So if today you feel like wearing a Lovely raiment, then if you've already gave him a Lovely raiment ticket, you can go back and change your Shadow Raiment to a Lovely Raiment. Basically, once you've used the ticket, it's always available to use a style for that item.

Accessory Closet
Instead of Accessories disappearing after being removed, or replaced, Accessories are added to a closet for you. You can go back to Bechamel and pay for him to re-equip the old accessory. The different colors and styles of the same item (ex. Dusky Bolted Vee and Military Bolted Vee) are still different items in the closet. Therefore one of your Dusky Bolted Vee could be on one armor, and the Military on another.

Sprite Reskins
Instead of having to buy a completely new sprite, you could take your sprite to the lab and pay 2000CE and they'll change your sprite to the desired reskin. Although, you must have a "Transformation Catalyst." A Transformation Catalyst will be an item taken to the lab with your sprite and used to transform it into the desired reskin. In example, you get the Black Kat Catalyst and take it to the lab, and they change your normal Serphynx into a Black Kat Serphynx.
