Killer coat can't be equiped in avatar?

I recently changed my armor, and when I try to equip killer coat as my avatar, I can't find it anywhere, like top and bottom are none, is it because killer coat is an overall set? (I'm new to the game, so I don't know much)

 

Only additional armors can be equiped as avatar. You can synth your armot to look like killee coat

 

Armors and avatars are different things. You do have the option to set the avatars you equipped to 'invisible', which makes your armor visible again.

 

There are two types of armors(armor app) in relation to avatar gears(top & bottom armor).
Whole armor are those armor app that get the default colored shirt when an avatar gear(lower) is equipped. Which ofcourse sucked for cosplayers wanna be's point of view.
Half armor is the one that is unchanged upper half when a lower ava gear is equipped(bikini ava gears wont be too fussed if you got screwed by pelulu and not get a matching colored busty bra with that sexy bikini, just dye an old swimsuit armor or light santa suit1 and just slap it)
Avatar upper gears dont affect your pants since there is no such thing as a default pantsu.(if you got them sexy avatar upper and looking for a pantsu lower and lucked out on bikini armor, holy pantsu... I mean robes is my top recommendation. Just sayin)

 

only Add. Gear can be put in the accessory slot and will be displayed in addition to your equipped Add. Gear.

the other avatar slots are for Avatar Pieces only and will replace the display of your equipped gears.

to make your armor look like Killer Coat you have to use Equipment Synthesis to change the armor's appearance.
