I do agree that it would be nice to be able to decide which part of a gear piece we want to show or hide with more toggleable options.

Another chest piece that could benefit from this besides the Skyworker's Singlet could be the Yakaku Dogi. While those chest pieces are great and I don't mind having a tattoo, it would still be nice to be able to toggle it on or off, especially for those who might not be fond of tattoos in general but who would like to wear this kind of clothes. I guess that another solution to this would be to release the same item without the tattoo, but to be fair it'd make us waste more glamour/inventory space so a toggleable option would be better.

I was also thinking of two hats that have nice pairs of glasses that we cannot find in game: the Isle Vacationer's Visor and the Varsity Flat Cap. The glasses are "attached" to the hat and you can only choose to hide or show them. I wish we could do the opposite and keep the glasses on while removing the hat. Otherwise, I hope we can get them added to the game separately at some point.

Last point I'd like to mention are dyes. We need more dyes as we are lacking a few options even though we have various shades already. We don't have bright oranges or fuchsia colours that are not metallic dyes. Also, we've been having new gear released during EW that had some kind of bronze/copper details, and yet we don't have those colours as a dye for ourselves (e.g. the Lunar Envoy's Jacket of Fending, Lunar Envoy's Justaucorps of Casting and other jobs). We can still try to use some shades of brown to match this "bronze" colour but it's not really the same and some items dye differently than others. Adding this colour as a dye would allow us to use other pieces of gear than the ones from the sets in question without struggling to find the perfect shade that matches.
