I have noticed that skirts sometimes have a pair of loops sewn on the inside, one on each side, and sewn onto the skirt below the waistband. They are attached at a single point, rather than at two points like a regular belt loop, and they do not appear to be drawstrings.
Do these loops have a purpose?
Ideas I had:
belt loops for an internal, hidden belt. But then there are only two, and I’m not sure that would work well in real life.
they attach to garters somehow.
they attach to suspenders somehow.
for attaching concealed items, such as keys or wallets.
They are vestigial, once had a purpose, but are kept because they are traditional.
Please forgive me if the answer is obvious - I’m not a girl.
They go on a certain kind of hanger, with the little loop looped around a special curve. Helps hold the skirt on the hanger.
Of course, I can’t find a picture of the kind I’m thinking of, which seems to always be clear, thick plastic with a metal bar, but here’s one that’s kind of similar: http://www.hanger-manufacturers.com/laundry-hanger.html
ETA: Curses! Foiled by searching for a picture.
Though your question has been ably answered I thought I’d add the useless bit of trivia that the material comes on a roll and is indeed called “hanger tape”.
Dresses come with those installed too. Sometimes uselessly, because dresses generally drape better on a hanger all by themselves without involving the extra loops, which just get in the way. It’s sometimes a challenge to not have the things hanging out of one’s garment. But they are useful for skirts because there usually isn’t any better way to hang a skirt on a hanger IMHO.
I keep 'em on, simply because while I have approximately 492 clippy hangers and only two dozen skirts, I’m amazed at how frequently I can’t find an empty clippy hanger when I need one!
