Fashion is all about self-expression. The fine print to this has to do with staying true to your personal style while still maintaining a pulse on what is — and isn’t — situationally appropriate. When it comes to the workplace, regardless of how casual the atmosphere, there are some general style rules that every professional should keep in mind. So take notes — and be prepared to scale back on those fashion statements at your daily grind as we run down the 20 things you should never wear to work.

Crop tops
A bare midriff has no business in the workplace. There’s just no work environment where an exposed belly button is going to get you anywhere other than the HR office for a lesson in workplace-appropriate attire.

Leggings
Comfy, cute and a staple in most wardrobes, leggings are the easiest go-to when you don’t know what to wear for an easy off-duty look. “Off-duty” being the operative term here, as leggings just won’t fly as part of a professional ensemble. Opt for sleek trousers, or, in the case of a super casual workplace scenario, slim-fit dark-wash denim.

Sheer clothing
If your undergarments are visible beneath your outfit, you can bet this is one look that’s not going to fly at work. No one expects you to hide those killer curves all day, but dressing for success is all about letting your work be the thing that shines through, not that sparkly bra.
Celebrities may be loving the sheer outfit trend, but remember, there’s a time and a place for everything.

Sky-high hemlines
Whoever said, “If you’ve got it, flaunt it” wasn’t implying you strut those bare legs around the office. Save the leggy skirts and mini dresses for when you clock out.

Second-skin pieces
Not only are you compromising your level of comfort, but skin-tight clothing may signal a lack of situational awareness and professionalism to colleagues and clients. It’s possible to flatter your shape without opting for clothing that clings to every curve for dear life.

Distracting prints
It can be challenging enough to draw focus toward your work without the added visual distraction of a dizzying print. Stick to flattering colours in solids or larger, neat prints to ensure your wardrobe doesn’t end up talking over you.

Sky-high heels
Spare the loud click-clacking through the office, and avoid taking an embarrassing spill by rocking heels you can actually walk in at the office. A kitten to mid-heel will still flatter any outfit, without sacrificing your comfort, or sense of balance.

Clothing with slogans or graphics
Save your political views, favourite sports teams, mottos to live by and funky graphics for your downtime and keep it strictly business in the workplace. YOLO may be your jam, but that shouldn’t be the message emblazoned across your shirt as you walk into that 9AM meeting.

Distressed denim
It should come as no surprise that torn, fringed, ill-fitting and just generally distressed denim is a no-no in the office. Not only is it too casual for any professional environment, it tends to reflect a lack of effort, which can negatively impact the perception of you in the workplace.

Sneakers
Trendy or not, sneakers are rarely an acceptable form of footwear at work. Save your kicks for out-of-office hours, and instead look to sleek loafers or cute close-toe flats for no-heel option from 9-5.

Distracting jewellery
From oversized hoop earrings to flashy diamond rings, anything that might be considered a “statement accessory” should probably be ruled out of your workplace wardrobe. Not only is it distracting to hear someone coming before you see them, thanks to those clanging stacked bangles, it also comes across as juvenile and potentially a little tacky.

Sweats
For obvious reasons — don’t roll out of bed and into the office. Just don’t do it. Put on some real clothes and save your sweats for home time.

Neon
Stand out at work for the right reasons, not because you’re dressed like a highlighter.

Cold-shoulder tops

Workout clothes
This one’s simple — before you wear workout clothes to work, ask yourself this question: “Do I work at a gym?” If the answer is no, get changed and get real about adulting. That muscle tee and those yoga pants just aren’t going to cut it as work-wear.

Stained clothing
Workplace or not, clean clothes are a sign of attention to detail and just general “grownup” effort. Do your laundry, wear clean, wrinkle-free clothing, repeat.

Sequins and sparkles
Save the flashy pieces for your next girl’s night — the office is no place to make a sparkly statement.

Distracting nails
From extra long nails to bizarre shapes, colours and designs, your hands can make an impression. Make sure it’s the right one with neat, reasonably-coloured nails that aren’t long enough to frighten anyone about to shake your hand.
Of course, if your office has a vibe where trendy manicures are cool — don't feel the need to shy away either.

Sunglasses
This one goes for any indoor space where you aren’t exposed to direct natural light. If you’re indoors and they aren’t prescription, take them off before your coworkers think you’re hiding a hangover.

Hats
Just like any formal setting, hats are a no-no in the office. Aside from being too casual an accessory to rock at work, it’s also generally considered disrespectful to keep your hat on when dealing with fellow co-workers, clients and higher-ups.
