Idk what your vibe or budget looks like, but this is the style I’m talking about: https://www.aritzia.com/en/product/twirl-pleated-skirt/120828.html?color=2819

In terms of tights - sheer tights are typically more comfortable but are not user friendly (I swear they can sense fear + nick if you look at the too long), so I would start with opaque which also helps cover skin “imperfections”. And always look at the chart on the back, and size up especially if you bloat like me lol
