A superb look which would work with any print or colour of midi skirt: an oversized (vintage if possible) denim jacket + white turtleneck (try an Adidas like Claire has) + fancy mules. 
Recreate Claire's look (kind of):
Denim jacket — Iro + Anja Rubik Nado oversized denim jacket, Denim x Alexander Wang Daze oversized Denim jacket, Daisy Street Oversized Denim trucker jacket, Topshop Moto oversized jacket, 7 For All Mankind oversized denim jacket,  or R13 Oversized Trucker jacket
Midi skirt — Whistles Miriam Stripe Midi skirt, Alice + Olivia Nikola striped poplin midi skirt, Gucci Pleated silk and wool-blend skirt, Sam & Lavi Allie Mid Skirt, Oasis Premium Stripe Prom Skirt, or Ace & jig Ra Ra Midi skirt
Fancy mules — No.21 Knotted satin mules, Paul Andrew Aristata peep toe mules, Charlotte Olympia Chrysie metallic mules, Kendall + Kylie Essie mules, Alexander White Eloisa mules, Balenciaga Rift rubberised neoprene mules, or Prada Bow-embellished mules
