Or: Things About Guys (and Things They Do) That Make Me Flustered, with various celebrity examples because I'm twelve.

fashion/style

• rolling back the sleeves of their shirts
  • ...which expose their forearms.
• wearing vests
• wearing glasses and looking good in them
• wearing Wayfarers
  • there is something about those sunglasses that I dig.
• snug-fitting (but not tight) shirts
  • "smedium".
• THREE PIECE SUITS.
• old school glasses
• wearing a cardigan without looking like Mr. Rogers
• wearing their jeans properly...
  • possibly with just a little bit of room for the top of their underwear to peek out.
• also on the denim front: jeans that are a little slouchy, but not baggy, and fit well in the back.
• cool forearm tattoos
  • I am a big fan of Liam Payne's chevron tats.
  • And Chris Evans's below his clavicles

physical

• thick eyebrows
• having low, rumbly voices
• good shoulder to waist ratio (I don't know how to explain it, but like--swimmer's type bodies, I guess? I KNOW WHEN I SEE)
• great smiles
  • ...which does not necessarily equal perfect teeth, even though those are nice. It has to be a smile with character; a smile that has personality!
    • like Chris Hemsworth has that big, goofy grin sometimes. That is a Smile with Character.
    • or Daveed Diggs
• lean but muscular bodies
  • ...just not veiny muscular.
• mouth mouth mouth
  • (ex: Eddie Redmayne, who just has this ridiculous mouth. And Chris Pine. And model Godfrey Gao, ZOMG)
• freckles
• green eyes
• speaking voices that have a smartass tone to them.
  • for example: Chris Pine in Star Trek
• let's talk about voices more and go with: suaveness/general cool to them.
  • like Armie Hammer or Lee Pace.
• great cheekbones
• broad shoulders
  • it's like an angle thing. Slopey shoulders just are not as physically appealing as, say, this is.
• booty booty booty
  • see: Chris Evans's introductory shot in The Avengers
  • or: Charlie Cox in 98% of the first season of Daredevil

miscellaneous

• reading
• kindness
• having feminist ideals
• being good with kids
• liking animals
• being dorky enough to be endearing
  • not Manic Pixie Dream Boy dorky, though. Not Dorkiness with Whimsy, just dorky but also cool.
• not a dudebro or a Nice Guy
  • Good Guys. Good Men. That kind of thing.
• politically progressive
• good conversationalist
• sports aren't his only hobby
  • I'm a movie/music/books/TV person with general interest in a battery of other things; I only care about sports a lot when it's March Madness or the Olympics. So a guy who is like, super-into a team wouldn't be compatible with me because my sports loyalties lie more with North Carolina teams when they're doing well or with swimmers/gymnasts!
• must love dogs
• charisma
• can you sing? MMM.
• the closer he gets to classically handsome while still maintaining some measure of geekiness... I want him more.
