Vestuário

Vestments of the Runecarvers pre-order pack cosmetic costume.^[1]

The costume cosmetics that are included in each month's pre-order set are indeed a full piece, and when you put it on it will cover your entire appearance. You will not be able to mix and match/toggle those pieces individually (other than your helmet) when you're wearing the entire costume. This is partially why there is a separate category for accessories - those are able to be worn/equipped on a more individualized basis, so you can mix and match to your liking!^[2] – Sarah Flanagan

Vestuário were available for purchase from the cosmetic store.^[3]

Full costumes do not mix and match pieces.^[8] – Steven Sharif

Costumes don't have a level restriction or require an in-game item to be obtained first.^[9]^[10]
Costumes are not gender or race locked, but can adapt based on a character's gender and race.^[11]^[12]^[13]^[14]
- Racial skins appear along with any costume appearances.^[15]^[16]
All hoods and head slot items, whether part of a complete costume or individual gear, will have the option to be shown or hidden on the character by the player.^[17]^[2]^[18]

Dyeable items

Dyes only affect tagged portions of dyeable armor or cosmetic items.^[19]

The dyeability of costumes depends on the specific costume.^[19]

Outside of wanting to keep maybe some identity from a lore perspective; for example if you have like a white lion's suit of armor, you may not want that white lion suit of armor to be black or blue. So, it's possible. It depends on the costume itself.^[19] – Steven Sharif
