Both ladies matched their beauty look to their clothing but I'll hand you over to our beauty editor Katie for further info on that front:
Holly and Jessie's looks go together like chalk and cheese. While Jessie did severe with a face-lifting, scraped-back top knot, Holly did the exact opposite by leaving her hair loosely tousled around her face.
The same rule applied when it came to their lip colour choices. Jessie made a statement with a glossy berry shade and Holly played things safe with a blush tint. If there are any similarities, it's that they both went heavy on the eyeliner (and that's stretching it).
So which look do you prefer, office chic or gothic glam? Let us know below and see more of Jessie's best style moments in her perfect 10 below.
