Marcia, Marcia, Marcia!
Okay, Marcia did have it going on, but so did Jan, and Jan didn't have that Homecoming-Queen-Gleam. She was more down to earth.
She had great '70s style and long, flowing hair. Those Brady girls sure did have amazing, straw-colored, straight hair, didn't they? My mother had naturally straight hair, but she tells me stories about other people breaking out irons to iron their hair straight, which sounds like a whole lot of work to me (although I guess people use hair straightening irons all the time, but that seems more sane than an actual iron and ironing board).
Jan had glasses. Whenever someone wears glasses, I love them a little bit more. Just because. Because of the glasses.
And she was sassy and wore groovy bell bottoms and great '70s shirts that I would LOVE to thrift. She's definitely the second-banana though. If you look through Brady Bunch promo shots, Jan is literally always covered by someone else -- usually Marcia or Cindy, and then it's just her poor bespectacled Jan head sticking out and smiling.
Oh well. Jan, you still have your place in history! You're a role-model for middle-children with glasses everywhere! (Or at least here. In my living room. Right now. For me. A role model!)
