The application of Adapted Costume and Kujo Jolyne (Cosplay) tags is tentative, and might be best served by Alternate Costume instead. Jolyne is just wearing one of her Jolyne Fly High with Gucci outfits, but Giorno does not appear in that story. Another she wore there was a full pink suit. I think what this artist had Giorno wear it, but with the pink shirt swapped for a petal-like white shirt to match her. Ultimately its something I am not fully certain of.
