Well, there is a right jolly old elf who is defined by his white hair, little round belly (that shook when he laughed, like a bowl full of jelly), and is covered in fur from his head to his foot, besides wearing a lot of red, but I hardly think that's the image you want to conjure up--your clothes are not tarnished in ashes & soot! (I hope you get the Clement Moore reference!)
"Eclectic" does seem to be a strong part of your style, as I've seen you refer to it on here numerous times. But "matriarch" and "practitioner" both refer to your roles in life, which could be carried out in various styles.
I actually think there is a bit of elfin playfulness to your style, but I've probably ruined any appeal that descriptor had with my opening line.
I just looked up synonyms for "playful":
frisky, jolly, fun-loving, lively, full of fun, high-spirited, spirited, in high spirits, exuberant, perky, skittish, coltish, kittenish; mischievous, impish, devilish, puckish, roguish, rascally, tricksy, prankish;
informal full of beans, frolicky;
dated gay;
archaic frolicsome, gamesome, sportive;
rare ludic
"she was in a playful mood"
light-hearted, in fun, in jest, joking, jokey, teasing, humorous, jocular, jesting, good-natured, tongue-in-cheek, facetious, frivolous, flippant, arch, waggish, flirtatious, whimsical;
rare jocose
Do any of those grab you? I think light-hearted, jocular, good-natured, whimsical, lively, and spirited sound like you, but maybe you feel drawn to another. You could just use "playful" and skip the synonyms.
You mention shoes and earrings. "Grounded" would refer to the footwear, and I think it reflects your personality too, as the responsible matriarch and practitioner. I wanted to look up ways to say "at both ends", tried "bookended"; that was frustrating. Most resources automatically changed it to the noun "bookend". Urban Dictionary gave a definition for the verb that really isn't your style, and there's a Psychology Today article about bookending & ADHD--also not helpful. My wifi really isn't cooperating enough for me to do more. But your shoes really are a big part of it for you, so maybe work them in.
