Paul Simon and Carrie Fisher
You youngs will not know this, but that Wedding Wreath is VEEEEEERRRRRRRRY 1983. I was a flower girl in many a wedding that required lil wedding wreaths. Carrie's feathered bangs are also very 1983.
Penny Marshall and Art Garfunkel
White lace to a wedding, Penny!??!?! I'm scandalized! (I jest; Penny Marshall could wear whatever she wanted to MY 1983 wedding, as long as it involved a monogram.) Art Garfunkel looks absolutely as expected. And this is our first DID THEY DATE?!?! The answer is yes and for a long time and I just did not know this! He said she helped him come out of a depression and parts of the internet think she helped him and Paul Simon patch things up (clearly not forever; aren't they currently not speaking?), and also I read that they once took a European bike trip, which IS the code for True Love.
Billy Joel and Christie Brinkley
This was clearly a fairly casual event, although 1983 Christie Brinkley of course looks like an actual goddess. Billy looks like he's gotten a nice tan over the summer.
Robin Williams and Valerie Williams
Is Robin Williams wearing coveralls? This feels right. (This is truly a slideshow full of TV stars who were well-known for their accessories, as Robin had just concluded his stint wearing those snazzy rainbow suspenders as Mork.)
Charles Grodin and wife Elissa Durwood
I feel like Charles Grodin ALWAYS looked EXACTLY like this. Forever!
Kevin Kline and Dana Delany
Kevin Kline looks like he's wearing one of those old jokey disguises of fake glasses with an attached mustache; Dana is adorable. I can't figure out if they dated but -- fun fact! -- Kevin's middle name is "Delaney" so maybe they're distant distant cousins. (Having said that, I think Dana and Phoebe Cates look somewhat alike, so Kevin may have a type.)
