Tuxedo

"Are you out of your mind? You can't wear that in battle! It's like saying to the enemy, 'Hey, here I am! Shoot me!'" The Boss

The tuxedo is a piece of extremely formal dress. It is often favoured as the uniform of choice by fictional high-class spies, like James Bond, causing it to become a staple of spy stereotyping.

Although most, if not all, of its appearances are non-canonical, the tuxedo is an unlockable item in several Metal Gear Solid games. It can be used in Metal Gear Solid and its remake, provided the player completes the game with both endings beforehand, starting each subsequent game with the new save.

A special set of VR missions entitled "Snake (Tuxedo)" are playable in the Substance version of Metal Gear Solid 2: Sons of Liberty. These missions contain James Bond-like background music, and are noticeably more challenging than the others.

In Metal Gear Solid 3: Snake Eater, it appears as an optional camouflage after completing the game once.

A tuxedo can be worn by Snake in DreamMix TV World Fighters.

Whilst not a tuxedo, a similar outfit known as the suit appears in Metal Gear Solid 4: Guns of the Patriots. It is identical to the tuxedo except that it contains a regular tie rather than a bow tie, and is unlocked by completing the game once.
