I get a Roz Purcell vibe from J's outfits - Roz can look a bit random at times, but at least she pulls from vintage/re-tailored clothing I suppose.
The psychedelic skirt just screamed Roz to me for some reason, fairly sure she had a similar colour palate recently. The top is gorgeous, but would have gone with a different skirt colour. Colour block as a commenter already said above.
I suppose J's still finding her style after years of the denim cut offs and fishnets
