Clothes Men Should Never Wear: Simon Cowell Is An Unbottoned Shirt Repeat Offender (PHOTOS)

For some reason, guys don't get as much criticism for what they wear as women do (see: Miley Cyrus), and yet so many of them don't have a clue how to dress or they just don't care.

Simon Cowell is one of many who sports clothes men should never wear. "The X-Factor" mogul (and Lauren Silverman's baby daddy) recently stepped out in a white collared shirt that was left undone so that us unfortunate celebrity-watchers had to gaze at his hairy chest.

This isn't the only time Cowell has purposely left his shirt open; the 54-year-old attended the premiere of the One Direction documentary wearing a a gun metal suit that left little to the imagination and he left his buttons undone at "The X-Factor" season three premiere, showing off bushy chest.

Guys: Unless a woman tells you to unbutton your shirt, please, for all our sakes, cover that up!

Unfortunately, the unbottoned shirt isn't the only offensive piece of clothing that guys and their celebrity counterparts wear.

Check out our list of clothes guys should never, ever wear. Ever! (And then head over to this list of stylish items guys should own.)

Unbuttoned Shirts

No one wants to see your chest hair.

Tank Tops

Unless you're pumping iron at the gym, tank tops should be left at home.

Chains On Jeans

You guys, it's not the '90s anymore. Move on.

Socks With Sandals

Stop trying to make socks and sandals happen. It's not going to happen.

Pleated Pants

Unless you work on the set of "Mad Men", you shouldn't be wearing these.

Muscle Shirt

We repeat: GYM. ONLY. Don't wear this outside!

Sports Jerseys Outside of Arenas

It's cool to wear a jersey while watching your favourite sports team at an arena or at home, but please don't wear them to work. They're way too casual and unprofessional.

White Socks With Black Shoes

Usually, black-and-white combos are chic but when it comes to socks and shoes, it's an eye-sore.

Baggy Jeans

If you can see your butt, then you've gone too far.

Harem Pants

Why would you even bother?

Too-Tight Skinny Jeans

Guys can definitely pull off skinny jeans but when they're this tight, it's time to go back and find a pair that fit properly.

Deep V-Neck Shirts

This one is just as offensive as the unbuttoned shirt.

Mock Turtleneck

If you want to wear a turtleneck, don't hold back and wear an actual turtleneck.
