There are two different versions: 144mb and 18mb.
This description works for both versions.

Was surprised that I couldn't find a LORA for my first oathed shipgirl, so I made one myself.
It was actually rather difficult to create a proper training set for this.

I am using AbyssOrangeMix3 (AOM3)

A weight at around ~0.7 is recommended, but other weights may also work in certain situations. Just play around with it and use what feels right to you.

The main prompt is "Essex"
You can try the following combinations for her outfits:

Base:

Essex, EssexUniform (Weight ~0.7)

A Trip Down Route 66:

Essex, EssexBiker, blue hair, yellow eyes, ponytail, sports bra, pants, open jacket (Weight ~0.7)

Brush and Ink:

Essex, EssexChinaDress, smile, blush, hair bun, double bun, blue hair (Weight ~0.7)

Craft Fairytail:

Essex, EssexPartyDress (Weight ~0.7)

Detective Essex:

Essex, EssexDetective, smile, happy, white shirt, fingerless gloves, midriff, necktie, skirt (Weight ~0.85)

Some outfits work better than others, especially for the detective one I couldn't really find a good amount of images. Of course you can also just give her whatever clothes you want, it should be quite flexible.

Used embeddings for sample pictures:
