That's what they're called -- shrugs. I couldn't remember. shrug
I've had that problem too with finding cocktail dresses with sleeves. Thank goodness when my stepson got married 4 years ago (or yikes, maybe it was 5), I was able to find a floor length dress with a bolero jacket.
We have a neighbor who makes clothing and has her own store. I might have her price out some simple A-line dresses with cap sleeves and a boatneck, nothing fancy. I'm desperate.
