In-universe, why did MiB uniform consist of black suits? Is there some significance to that attire?

And, why only black suits?

Zed: The last suit you'll ever wear.

It would seem that their type of job, they would need to sometimes blend in - wear casual, or other kind of suit, or fake police uniform (rarely black).

    In-universe answer: They're government agents and there are no casual Fridays. – Carpe CM Nov 13 '15 at 17:21

    Because if the suits were green, they'd have to change their name to Men in Green :P – Salmononius2 Nov 13 '15 at 17:42

    @Salmononius2: That's actually part of Mercedes Lackey's "Elves in LA" series. The government organization got help from one of the bane-sidhe to have suits that make them invisible to the fae and it just so happens that the material is emerald green and can't be dyed. – FuzzyBoots Nov 13 '15 at 18:29

To look like the FBI

The MiB frequently impersonate the FBI as part of their cover.

KAY: Give her time to get the wrong impression. Makes it smoother.


KAY: Yes, ma'am. I'm Agent Manheim, this is Agent Black, FBI. We'd like to talk about your visitor. - Men in Black - Subtitle Transcript

Since the public's impression is that the FBI frequently wear black suits (which is in fact true), it makes sense for MiB agents to do so as well.

To look as non-memorable as possible:

Zed identifies that the goal of an MiB's attire is specifically to prevent strong memories from being created:

Zed: You'll have no identifying marks of any kind. You will not stand out in any way. Your entire image is crafted... to leave no lasting memory with anyone you meet.

To conform to the myth

In the source comic, it's made clear that the reason why they wear black suits is because the myth is that the MiB wear black suits.

enter image description here

So that people will remember the suit, not who was wearing it

Zed said, "Your new image is being crafted so you don't stand out."

"I dunno, up in Harlem, that suit might make me look like a Muslim. Fit right in with Brother Farrakan and the Fruit of Islam."

Zed ignored him and continued: "You won't leave much of an impression in anybody's memory. What they probably will recall, if anything, will be the suit." - MiB: A Novel - Steve Perry

    Well done, sir. – Mindwin Nov 13 '15 at 18:31
  • Next question: Why do the FBI mainly wear black suits? – Pharap Nov 15 '15 at 9:22
  • @Pharap - Because if they wore white suits, people would get them confused for the 'Man from Del Monté' – Valorum Jan 1 '16 at 14:08
  • What is that FBI link supposed to link to? Just the top level faq? – Todd Sewell Jan 4 at 17:36

    @ToddSewell - It used to contain some info about the FBI 'dress code' for field operations which mentioned the wearing of business attire. Since that's gone now, I've removed the link. It was only for background anyway. – Valorum Jan 4 at 19:05

Obvious answer, they're meant to be the prototypical Men in Black which UFO folklore has covering up incidents by altering the scene and eliminating witnesses. Why black suits? They're associated with government figures due to a combination of formality requiring regular wearing of suits and low wages meaning that a government employee only owns so many suits — dark suits don't show stains as badly, so you can wear them more days in a row. Therefore, government agents, or beings want to look like government agents, would show up in a dark suit. In addition, you have the association of black with mourning clothing, which means that this monochromatic sartorial styling adds an association of death and lack of humor to the agents.

As to why the MiB of the movie universe haven't moved on to something less conspicuous, for one, the legends of dark-suited men coming around for strange happenings simply provides a standard uniform. People are likely to listen to someone who looks suitably governmental. Lastly, it provides a standard uniform for the group, providing a sense of unity and belonging, and I can vouch from experience that governments take a long time to change their stylings.

From a practical standpoint, suits make for lousy field clothing — they tend to be hot and restrictive, and the risk of damage in the field means you'd generally prefer to be wearing something else if you face combat. But in the context of supertechnology, a full suit makes sense because it covers much of the body, allowing you to hide armor, and typically includes many pockets, allowing you to hide more gadgets. The usual liabilities of heat and restriction are dealt with by futuristic materials.

    @Axelrod: His point is well-taken in a chicken-and-egg viewpoint. We have legends of the Men in Black in our universe, which means it makes sense for the fictional characters to be the same thing, but presumably, in this universe, they are the genesis for the folklore. – FuzzyBoots Nov 13 '15 at 17:18

    @SeanDuggan What else would you expect government agents to wear? We'd have urban legends of Men In Hawaiian Shirts if the FBI and CIA had looser dress codes. – Carpe CM Nov 13 '15 at 17:30
