This specific LORA (non-celeb) is not intended to replicate Jennifer Connelly or her Character Jenny Slate from The Rocketeer (1991), but rather the dress she wore at the South Seas Club. It's possible to have some semblance but it seems to be more the default hair color general vague appearance.

I accidentally created a version that does retain her likeness, see (Celeb) version up above for the one that retains her likeness Nevermind it'll have to be a separate post I can't separate this one from the other one in a way that wont freak out the censors

Described from Propstore:

Jenny Blake's (Jennifer Connelly) satin ball dress worn in Joe Johnston's The Rocketeer. Jenny wore this signature dress while attending dinner with Sinclair (Timothy Dalton) at the famous South Seas Club. This bespoke dress screen matches due to unique stitching detail around the shoulders, down the sides of the dress, the ‘V’ cut at the front-bottom of the dress and the zipper line running down the left side of the dress.
