What is this weird blue garment (or nongarment)?

That is bizarre. It reminds me of a tube top, but it would have to be for a small woman.

A skirt for a child.

Toilet paper cover? You know for spares?

A stretchy knit cover for a table lamp?

What else could it be?

Nice watch, by the way.

Also, could be a cover for a cast. Ever remember breaking a leg?

A penis warmer.

Maybe a neck gaiter?

It looks like a cozy for some type of object, rather than a piece of clothing. My Grandma used to have cozies on all sorts of things, including the toilet paper rolls and the toaster. Maybe it’s some type of coffee thermos cozy.

Here is a picture of a Coffee Pot Cozy

I have seriously seen cozies for vacuum cleaners, too. Could it fit your vacuum cleaner? Maybe just the bag holding part?

It’s a thick woollen knit 18 inches long. It gathers at one end and ties at the other. I can barely pull it on over my head, and it would choke me if I tried to wear it.

No one who knows me would give me a cozy for a vacuum cleaner.

I suppose this could go over a cast, though I’ve never seen anyone with one. (I did buy a toe cover to wear with my foot cast last year because that’s what was exposed.) When I had a cast on my leg after knee surgery back in the seventies, someone might have given me a cover, but no one did.

(John, I’m dying to know why someone might enclose a table lamp in a knit sleeve. Do you know people who like to keep their lamps warm?)

@chyna Really? That’s hilarious. Why would a vacuum need a cozy?

@augustlan My best friend’s mother had one for hers. She had cozies for everything. It was crazy.

It could be a neckware for winter, the tie could be for when blowing wind is involved on top of the cold air.
Or a leg warmer for an overweight person? (since it’s not tight at the top and bottom, someone’s fisrt attempt maybe?)

Perhaps similar to a leg warmer but for the arm from elbow to wrist only. You could have a matched pair or contrasting colors.

You wear it, of course, with a woolen short-sleeved turtle-necked sweater.

Check to see if it fits over a roll or two of toilet paper. It could be a cozy for that.
My grandma used to crochet them like little doll dresses. The dolls legs would go in the hole of the roll and the dress covered the around the roll..

Dachshund sweater.

I vote for toilet paper cover. And if you wear an analogue watch, do you carry a separate stopwatch? I couldn’t live without my stopwatch.

The joke answers are cute, guys, but I really want to know, even if this is in Social.

Who would knit a warm sweater to hold a stack of 4 rolls of toilet paper that just fall out the bottom if you disturb it? Eighteen inches is pretty long!

And as I said above, if you can even get it over your head, it’ll choke you.

Stopwatch, @rooeytoo? What for?

Other than the TP cover, and I was serious about that, could it be a leg or ankle warmer. Sort of like was popular back in the eighties? Maybe someone was knitting them and only finished one?

Could it be… a wine bottle sweater? (No idea why you would want to keep your wine warm of course!)

Here is another example (some people have way too much time on their hands).

Or a big water bottle cover

Or a stump cover (perhaps someone got confused when you broke your arm?)

Here is a site full of amazing, knitted wonders

Am I reading correctly that it cab be tightened at both ends? I’m interpreting the word gather to be adjustable to a degree?

I see the end with the bow and assume that its not merely decorative but functional as well.

My best guess would be as storage for plastic bags, scrunched up and able to be pulled singly from one end. The ones ive seen in catalogs look quite similar to this except that they’re made out of cloth rather than knitted.

I was thinking the same as @Bellatrix. A bottle cover of some sort.

I’m intrigued.

No—it’s open at both ends. The ribbed end is more than twice as wide as a sweater cuff. This thing would hang loose around any normal bottle and droop over at the top. My details above said it wouldn’t hold plastic bags. The bottom end is wide open like a watch cap. I have one of those plastic bag holders, a cotton tube with elastic at both ends and a little loop to hang it with. This is utterly different.

The drawstring end can close in a bunched-up kind of way, but why? You wouldn’t untie it to remove it from something when all you’d have to do is pull it up and over.

And it’s eighteen inches long. Half a yard. Fully the length of my arm from my shoulder to my wrist. Look at your arm. Do you have any bottles that long? Ok, maybe a Galliano bottle, but it’s the wrong shape, and who would put a sweater on a bottle of Galliano?

I don’t know that we can count on there being any logic to this thing @Jeruba! I wouldn’t put a sweater (or bottle cosy) on a bottle of wine. Apparently people do though. I did wonder about the length and the thought of a Galliano bottle did cross my mind… but the logic escaped me too.

Long, woolly, open-ended with a drawstring thinking cap back on…

@Bellatrix, I have to give you bonus points for your “knitted wonders” links. I read all of them but didn’t look at every one—this is just plain not made for golf clubs or tissue boxes. I declare the Lace Balloon Cover to be the winner of the Fruitcake Award.

Still no cigar, though.

I use my stopwatch to time my runs, or soft boiled eggs, or a steak on the grill, so many uses.

Oh—I keep half a dozen kitchen timers around for such purposes.

I never leave home without my postmodern leg warmers. Are you by any chance an amputee?

I… Er, I mean… Some people make cozys for everything.

I like this one! Sorry, @Jeruba , I have no idea what your mystery object might be… maybe you could use it for a Swiffer cover, though. Although I guess you’d have to cut a hole in it, or something. I don’t get knitting covers for those, anyway; I would just use a towel or something if I were inclined to make anything of the sort.

I think it’s a child’s dress. A very old-fashioned one made by a novice knitter who wasn’t really following any sort of pattern.

Just by coincedence, a young lady at work was wearing 2 knitted arm warmers that were pretty much exactly the length that you are describing on Friday (minus the decorative bows). I had never seen anything like them before the Q came along.

She had on a regular short sleeved T-shirt, then the knitted arm warmers went up just past her elbows, and then she had a flowy light weight, mid-arm length jacket/sweater over that, so you could see the arm warmers poking out of the jacket sleeves. It was a layered outfit.

I probably would not have noticed them, except one of them fell onto the ground when she was grabbing her purse and her gear out of the car in the morning.

Smurf’s sleeping blanket.

Lace Balloon Cover, so funny. Based on the links in the answers it could be just about anything! Were you in the hospital for while with something serious and someone who came in to help out left it there, forgot all about it?

The hospital comment above made me wonder if maybe, at some point, you’ve ever had a cast on one of your limbs. Perhaps someone made it for you to put on that? To keep it warm or something.
