Tuxedo

Tuxedos are full outfits (a full set) that can be bought from Seymour in the Village underneath Taylor's house. They are one of the few sets that don't have a helmet. Any three of the suits are used for the Romero and Juliette quest as the final task.

Wearing the Elegant Tuxedo gives the Achievement Glass Cannon.

Tips

 * If you find yourself constantly dying with this armor set, use a Bonzo's Mask as a helmet as it gives you double lives in dungeons. However, if you aren't going to do dungeons with this set, you can opt for a Spirit Mask.
 * If you want to buy this armor set for the Romero and Juliette questline, buy the Cheap Tuxedo as it is the cheapest out of all of them. Hence the name "Cheap" Tuxedo. If that is still too expensive for you, consider buying it from the auction house as it can go for about cheaper. Or, if you don't want to do either, you can borrow it from someone.
 * The damage from the full set bonuses are part of the additive multiplier, hence the actual damage increases are much lower in percentage.

Suits

 * Each Tuxedo set has a slightly different colour, the cheap set has light grey tint, the fancy one, a dark grey tint and the elegant set is black.
