I mean really, it's a maid outfit, with a pretty poofy short skirt. I dont even think it's my first one. It's trained on the little more Sissy/Fetish side, but it's still maid outfit DNA.
Satin/Latex/Crushed Velvet, you know the drill.

The Pony version is https://civitai.com/models/259860?modelVersionId=566562
but it came out flatter (and I fucked up) there so I left it there.
TL;DR
wearing dr3ss, blue satin maid outfit, short skirt, poofy, ((voluminous wide short skirt)), frills, apron, platform heels, ankle bows, thighhighs
realistic, photo while NEG: anime, 2d, 3d, render for best results in some models
For best results, realistic can help, but it largely depends on your model. Some illustrious models are pretty hard into anime which can lower the power of the crinoline or whatever the skirt is "poofed" by. YMMV
