The basic answer to the headline’s question is, promoting her new movie Jolt, which stars Kate Beckinsale as, ahem, “[a] bouncer with a slightly murderous anger-management problem that she controls with the help of an electrode-lined vest she uses to shock herself back to normalcy whenever she gets homicidal. After the first guy she’s ever fallen for is murdered, she goes on a revenge-fueled rampage to find the killer while the cops” — aka Bobby Cannavale and Laverne here — “pursue her as their chief suspect.” (Yes, of course Stanley Tucci is also in this, because Stanley Tucci is in everything. I think that’s a verifiable pop-culture fact.)
There’s a germ of something chic here in this outfit she wore to the premiere, even if in execution it looks like she just repurposed one of the Jolly Green Giant’s undershirts. But it’s also light years better than what she wore to some Jeannie Mai “boozy tea party” earlier:
I have a LOT of questions about this outfit, obviously, but first and foremost: Why would one wear a belted catsuit to a BOOZY TEA PARTY? Booze and tea are diuretics! Odds are if you are consuming booze, tea, or BOOZY TEA, you will need a restroom fairly soon, and that outfit is many, many things, but “bladder-friendly” is not on the list.
