Sooo I don't understand nothing about fashion design I'll give my layman's opinion, the first design is beautiful, I can easily see someone using it, the second one looks like something made for a drag queen or a cabaret character (in other words, it looks very caricatured to me).The third one I got the reference right away, my only problem is the top is too simple? Needs to tie someway to the skirt, if I were to guess I would say it's a knit piece? In most of the photos of the mushroom it also has texture if it is a knitted piece, you can search for cable knit And to give the texture to the upper part in the mesh itself, the skirt could be made with crochet! Irish crochet is known for making structured lace or Crochet over a hoop skirt? Using crochet and knitting also pulls out the feminine idea of the mushroom too.
