I've just finished watching all the films of four of my great contemporary loves, three in adaptations of Jane Austen (all of which are superior to the actual film versions, in terms of script and especially female beauty):
Alicia Silverstone in Clueless/Emma
Camilla Belle in From Prada to Nada/Sense and Sensibility
Aishwarya Rai in Bride and Prejudice
From the "deep structure" of Austen/Shakespeare:
Odette Yustman/Annable (and Kristen Bell, among many other greats) in You Again
And a severe plot-outlier from the deep structure of the romcom:
Ali Landry in Repli-Kate.
Although I'd seen all these cited films years ago, with my wife free from work chores, I watched them again with her, plus the other romcoms of these gorgeous women:
Sundown, Open Road: Camilla
Mistress of Spices: Aishwarya
The Truth About Lies; No Sleep 'Til Christmas: Odette
For those restricting themselves to (neo)noir, then check out:
Camilla in the remake of the 1979 original, When a Stranger Calls, and (with Elisha Cuthbert) in The Quiet.
Odette in the remake of the 1970 original, And Soon the Darkness, and in a lesser role, The Double.
These are films my wife won't watch but you may want to.
FYI: Camille and Odette have been celebrated as major beauties; Camille many times so. Of course Aishwarya is in a galaxy all her own: Miss World 1994 and perhaps the most esteemed/awarded actress in the past quarter century in India, to say nothing of its most celebrated beauty. Unfortunately, nearly all her films are either in Hindi or Tamil, and, of her five English films, she only matters in the final third of Steve Martin's Pink Panther 2 and is not at all worth our attention in The Legion. Provoked, the true-life story about a battered-woman case in Britain, which changed UK jurisprudence, is one of the best ever of all women's pictures. Still, to go toe to toe with Alicia's iconic performance (so superior to Paltrow and Taylor-Joy, just as, similarly, "Ash" is so superior to Garson and Knightley, and just as Camilla is so superior to Emma Thompson), I believe all these women, because of both their exceptional talents and looks, very much deserve our attention, whether limited to their (neo)noirs or broadened to their romcoms.
