Degree in which lace or lace-trimmed apply to posts

Using lace-trimmed skirts as an example, I must ask- to what extent of decor or complexity must be present in a trim for it to be considered lace?

Should these posts qualify? Or is there a bare minimum other than "triangles" or "repeating pattern"? The wiki for lace says Lace is a delicate fabric, usually colored white, containing intricate web-like patterns. Lace trim merely states Any article of clothing that has lace trimmed around its edges..

I've searched a number of forum topics (topic #17342, topic #21989, topic #31227, topic #14098) but none of them quite go in-depth on what level of detail must be present.
[EDIT] Oh piss I forgot that Beako post lacks the trim on the skirt. It's on the ribbons and gloves though.

Speaking only from personal experience, if I were posting these, I would maybe tag your second and third examples with lace trim and not the others.

https://en.wikipedia.org/wiki/Lace

Lace is a decorative openwork textile made without the use of pre-existing fabric.

https://en.wiktionary.org/wiki/openwork

Any of several forms of metalwork or needlework having decorative openings.

All the lace examples on Wikipedia are quite decorative.

From the linked images, I'd call the second and third lace. The first, fourth, and fifth are something else; they're not openwork, but I don't know what.

Well, what do you tag the other posts as, then?

I said I don't know

Maybe a good name for this tag would be "triangle_trim" or "triangular_trim"?

I tried looking up what this type of trim is called, and the closest thing I found was "pinking" (Link: 1, 2)
I couldn't find anything similar on Danbooru. It's not frills or lace.
We could try creating a tag like pinking trim or sharp trim, unless someone has a better suggestion.
