I'm in the mostly practical and depends on the definition group.
I looked up a definition, and it referred to focusing on the USE of an item.
So I'm definitely in that camp, generically speaking, for clothing--it's meant to be used. Art is "experienced" through the senses. Clothing provides sensation, but just looking at it on a hanger is not enough.
Some care-taking is not over-limiting to me so I will dry clean some things and hand wash some things. But I do evaluate that for whether I can get the same style bang for less care-taking.
I think the things I see that really say "impractical" to me are those items that are unlikely to survive careful cleaning, or day to day wear. Things that will fall off, or break off, or yeah, right, find a dry cleaner that can handle THAT.
Jewelry and different belts and so on are ornamental--well, belts hold up pants and fill the loops, but YKWIM--so they're not practical, meaning, you don't NEED a necklace, they're decorative, but in a very wearable way (chosen for wearability).
I do have the odd low-ish heeled pump or 2 for dress-up occasions, that are comfortable for an evening but not for work. So, that is not full-comfort based but fits the USE desired for the occasion.
Clutch purses, same thing--not practical for many occasions, for me, but good for a few.
So although I generally skew very practical I can see quite a range based on tolerance for care-taking of clothes and also comfort--meaning, some people really are comfortable in pumps (some kinds of) and so there is nothing impractical for them about wearing them (well, not on the farm, of course).
When I think impractical, I don't as often think of clothes I see on the rack, but tend to imagine really weird things like some of the exaggerated runway styles of crazy fabrications no one could maintain, or buckles and chains you can't sit in, or Flying Nun hats or something.
