Your clothes should fit your body—period
“In my opinion, it's more important that clothing fits really well than be a particular style,” answered srhizbth731. “That's what's really going to make you look fantastic. What I objectively think looks great is either a well tailored suit or the classic ‘fitted button-up with the sleeves rolled up’ thing.”
Others agreed on this point.
"Wearing clothes that fit is almost always the number one suggestion for guys and an easy fix, yet sooooo many dudes protest it. I'll never understand it," Ayyyyyymaaan wrote. "If you wanna be buried in your cargo shorts and graphic tees, that's your choice."
Don’t let your pants fall down
From steingrrrl: “Finally, wear a belt! And if you're wearing a black belt, match it with black shoes, and the same rule applies to brown.”
That last part's a little flexible, but overall that's one rule you can't slack on: Unless you're wearing athletic shorts or a suit, you should probably be wearing a belt.
A good tee goes a long way
From ciabella88: “I love when a guy wears a nice fitting basic black tee, does it for me every time.”
Get some nicer outerwear that’s not your old puffy jacket
From allthebacon_and_eggs: “Guys in sexy, cozy winter coats. Peacoats are a winner for me and immediately make me want to snuggle up.”
Keep wearing your henley

Your shoes and accessories are as important as the rest of our clothes
“Well fitting chino, nice shirt-tucked in, sleeves rolled towards the elbows. Showing a very nice wrist watch,” blacchic wrote. “Suede/leather Chukka boots. Makes me weak at the knees-always.”
Make sure to roll up your sleeves
Even guys weighed in on what women said they liked about their outfits. “My wife said one of the times she was the most turned on is when she was watching me fix a light switch in the bathroom,” Spider-Ian wrote. “I was wearing jeans, white t-shirt and flannel with rolled up sleeves. She later confessed the rolled up sleeves are sexy because it looks like we mean business.”
Simple statement pieces are key.
Buy that jacket you like
From ayyypokkai: “You can never go wrong with black or dark colors. A fancy jacket with something simple underneath would make you look good with minimal effort. Also, please do wear pants that fit well.“
With the jacket, don't go too "fancy," though.
Have a good suit on standby
"A well-tailored suit," operarose wrote. "Gentlemen, it's like lingerie. Invest in at least one and your life will change."
Wear sneakers that you don't use for deadlifts
From ravekitt: “I don't know if someone has said this, but wear decent shoes and keep them relatively well maintained. I see a lot of younger guys wearing nice casual clothing but then pairing it with their kinda worn out gym shoes. Nice sneakers can work well with the right outfit but I think you need to make a distinction between casual sneakers and actual workout gym shoes."
She's always going to notice your shoes, so find a pair you're comfortable enough wearing to work or on a date.
