On Pixiv, the tag アメリカンスリーブ (American Sleeve) is used to denote a kind of sleeveless clothing where the armholes are cut near the base of the neck to the lower armpit, leaving a large portion of the shoulders bare. This is also typically a Sleeveless Turtleneck.
This tag may be used for tops with Detached Sleeves, but not for Strapless, off-shoulder, or Spaghetti Strap tops. See the differences below.
