The 1998 Premiere of Halloween: H2O

Michelle Williams

I, too, owned this exact look, although I paired my dress with a vintage-feel cardigan. I promise you that, although we cannot see it, there is very likely a small whimsical bejeweled barrette in her hair somewhere.

Josh Harnett

Josh Hartnett's nascent PR team neglected to take his drink away from him on the red carpet. They did, however, get him a decent coat that I hope he still has...even if they did make him wear it in LA in July.

Jessica Biel

What we've learned this week is that Jessica Biel truly was a walking Delia's catalog at one point.

Jamie Lee Curtis and Janet Leigh

Jamie Lee Curtis looks timeless and streamlined, as usual. Janet Leigh looks appropriately movie star-esque.

Tony Curtis and then girlfriend Jill Vandenberg

VERY sensible of Tony Curtis to make sure he's got his ticket there in his pocket; it's quite nice that he came out to support his daughter and ex-wife, and also I would have liked to hear JLC and Janet discuss Jill's sartorial decisions for an event where she's meant to support her boyfriend's daughter and ex-wife. (, so....)

Marisa Coughlan

This photo contains not one but TWO iconic handbags of the late '90s.

Jodi Lyn O'Keefe

Did she and JLC plan this? Having noted that: This has aged very well and she looks totally reasonable. Fun fact: Wiki tells me that she's a "licensed bounty hunter."

LL Cool J

I love that LL seems to be saying, "WHY AM I HERE???" to the camera. Because you are a patron of the arts, LL!

John Ritter and Jason Ritter

This feels very sweet. John Ritter is quite missed.

Christina Ricci

As previously discussed, the late '90s truly were a heady heyday for fine leather goods.

Jason London and Charlie Spradling

They were married until 2006; I was about to note that his Wiki does not mention many of his problems with addiction, but that is in fact his twin, Jeremy. I hope they're both doing well now! He does have a lot of stuff on his IMDb upcoming -- of varying degrees of quality, but it pays the bills!

Jennifer Aspen

This aged pretty well.

Jason Isaacs

SO DID THIS.
