The specifics of fabrics can often be confusing for lolitas, even experienced ones. Lolita material discourse typically centers around the primary polyester vs. cotton divide, with adherents on both sides. Rarely does the discussion cover the specifics beyond the fiber content. I've covered the basics of lolita fabric in my old school post series, in which I divided the identity of a fabric into four components: fiber content, weave, all-over dye, and print. Any fabric can come in any color or print, but weave and fiber content define a fabric.
Organza (and organdy, which is a variation thereof) is a tricky fabric to deal with. Despite having been a minor part of lolita since its inception, and having many uses, it's a real pain to sew with, and can fail in new and interesting ways that small-scale brands may have trouble managing. Because of this, organza was seldom used until after the OTT sweet boom. So, this unique textile is a perfect introduction to why fabrics are more than just an aesthetic choice.
