Dress code for the IT field.

kohr-ah

At the MSP it depended your client and department.
Hospital client was button up, tie, dress shoes, khaki
University client was Polo, khaki, dress shoes (loafers)
Home office was Polo, khaki, dress shoes except Fridays was jeans, t-shirt, tennis shoes

Fortune 500 is long sleeve button up, khaki or dark jeans, dress shoes. (used to be polos or short sleeve button ups until our CEO said men in polos look like trash and changed the policy in 1 day and sent people home if they weren't adhering to the dress code the following day. Unpaid)

I've always worn a dress shirt, tie, black/tan/blue dockers, matching belt and polished black steel toe boots.

I feel you must dress the part to look like the professional you want to be conveyed as.

Lastly, I don't see many people mentioning it but I personally work-out at the gym 5 days a week and run on the treadmill for 6+ hours a week. I feel staying healthy is just important as how you present yourself in the business place; being healthy and fit has a positive effect of conveying confidence in yourself too; that's my 2 cents.

I'm an IA Engineer for the Air Force (contractor) and our dress code here is business casual, seems to be the case with most IT places. So here anything from dress pants/button-downs to khakis/polos are acceptable. So regardless, it wouldn't hurt to stock up on khakis and polos. I'd also recommend getting a pair of brown AND black dress shoes and a nice belt (the black/brown reversible ones are great). Ties tend to be overkill but wouldn't hurt to have some for other occasions.

I'm a system operator on a DoD contract, and typically wear a button up long sleeve of some checkered or stripped design, brown casual-ish dress sneakers (is that a thing?), and loose fit dickies, either khaki, black, gray, or dark denim. Facial piercings come out, plugs stay in, no other jewelry, no visible tattoos. Glasses so I look extra smart and less threatening. Skinny Puppy hoodie when its cold.

Polo's and khaki's.

Business casual...polo or button up and dress pants. I work in Infosec...don't move equipment generally.

I'm about 60% office and 40% field work these days, but it's pretty casual either way. Typical day I wear short sleeve button up shirts (plain or band shirts (nothing obscene), cargo pants, and skate shoes. I have visible tattoos on my arms and my boss doesn't mind it as none of them are in "bad taste". I take out all facial piercings except for earrings and tiny nostril stud. Sometimes we have more relaxed days (around the holidays usually) and I flip my septum piercing down. The network engineers here typically wear jeans (some are old school and wear slacks) and button up shirts. I'll wear long sleeve button up if I know I have a important meeting that day. This is in the public sector (education).

I get the feeling location matters more than job title.

Vancouver, BC.

Current job - DevOps Engineer. On my first day, I wore standard hipster wear (plaid shirt, light beard, skinny black jeans, beanie). A Silicon Valley-style jeans + hoodie is acceptable here as well. Dress shirt + nice sweater = borderline overdressed. Only VPs wear something as fancy as slacks/khakis + dress shirt.

Previous job - Linux System Administrator. Let's put it this way - our CTO wore sweatpants and a t-shirt. On a good day, the T-shirt was new. On a bad day, it looked like he was just painting his house. The dev manager at that place wears Hawaiian shirts and heavy metal band T-shirts. Only the CEO, CRO, and project managers dressed well. Even the CFO gave up at one point and started wearing a random polo + jeans. I typicall wore jeans + a dress shirt + either a zip-up hoodie or a Banana Republic wool sweater. On a good day, I ironed the dress shirt.

Before that... ooh boy, anything above gym shorts/sweatpants was overdressing. Technician (at a data centre).
