When I first started working on the design of the Mage for Arlecchino, I immediately imagined voluminous sleeves and a mermaid skirt. I think this style is very suitable for Arlecchino.
The costume turned out to be multi-layered and the fabrics for each layer can be the same or different. I like the options - satin, velvet, leatherette, jacquard.
Chiffon skirt, tulle. Lace can be used for patterns.
In my opinion, beads, lace and sequins will look great here.
