What would you like help with?
Her pants can probably just be basic blue capris. Her top however would have to be made from scratch. For that i recommend looking at eithrr haltee top or dress bodice patterns. Whatever you do the pattern will have to be modded to account for the harness for the wings and the side slits
youll have to be careful of the top riding up. Some velcro in the waistband of the pants will help
Her wings? Tutorials there are lots of them literally just search cosplay wings into da or Google and pick your fancy
Her wig could probably be found on arda-wigs in the medium section
Hope this helped:3
