1. Steven's PB is pretty accurate (especially those eyes), but I have to be careful about how I choose icons for him. Steven's a little leaner than Jensen is on Supernatural and is a little bit more reserved, and he rarely wears plaid, so there are definitely times where he looks absolutely right and times when he looks absolutely wrong.
He's a pretty big guy, with broad shoulders and comparatively slender hips, and he's noticeably bowlegged. (If you google search "bowlegs" you will find nothing but medical photos/diagrams and pictures of Jensen Ackles. I'm not even fucking kidding.) When standing straight, his knees don't touch, and while this really isn't a problem in his leg function at all he does get a little stiffness in his knees -- and his bowlegs contributed to needing a knee replacement earlier this year after his injuries.
But he's not... really stacked. He's muscular, but he's not all ripped like his dad, or all lithe and lean muscle like his mom. His body is actually rather soft, he's got some body fat to him, and while he's clearly well-built he doesn't look like some marble statue of a man.
You can't see it in the icons even though the PB has them, but Steven's got freckles. They're very faint, but they're dusted all across his nose and cheeks, over his shoulders. When he gets tan, the freckles pop a little more.
He keeps his hair trim, as a rule, and while he's usually clean-shaven he can let some serious stubble come through sometimes. He doesn't fuss about his body hair, but ... he actually gets rid of the hair on his chest, and he doesn't tell anyone that he does it. He just lets people think he's naturally smooth there.
2. Neutrals, the occasional (very occasional) plaid button-down. He's usually in jeans and a black t-shirt with some kind of jacket. Gray t-shirts, too. Sometimes gray long-sleeved shirts. Black, gray, with blue or army green jackets. He prefers v-necks over crew-necks, unless they're kind of loose and worn out. His style is exceptionally unexceptional, but his clothes fit really nicely and despite being boring are actually incredibly expensive. He makes a lot of money. A ~lot.~
He doesn't like to wear suits, but he looks damn good in one, especially a tuxedo. He just doesn't like to go in for formal wear or business wear. It's really rare when you catch him in the classic black suit and tie that most SHIELD agents like to wear.
He's not really a hoodie guy unless he's lounging around the house in pajamas. Plaid pajama pants or boxers and t-shirts.
For underwear it's mostly fitted boxer-briefs, nothing bunchy or baggy. He's also a little bit superstitious about his socks? He's just kind of particular about the kind of socks he wears (black, super soft, not too thick and not too thin) and it's the only thing he WON'T change when he's undercover.
