Tank tops are shirts without sleeves, so they should in theory be tagged as sleeveless shirts but for some reason they don't count?
That probably has a lot to do with topic #12487, where the question of whether tank tops should be tagged as shirt was left without a satisfactory answer. I don't personally see why they shouldn't, since in practice nearly every other sort of upper-body wear from blouses to crop tops to sweatshirts gets tagged shirt on a routine basis.
IMO, all tank tops are sleeveless shirts, but not all sleeveless shirts are tank tops. For instance, there are sleeveless t-shirts ("muscle shirts") with narrower neck- and arm-holes than a tank top would normally have.

Is a camisole always a tanktop (or viceversa)? Should they be implied, or are they completely different?
The most obvious distinction is strap width; camisoles have spaghetti straps no more than about 1 cm across, but tank tops have straps that are usually 2-3+ cm across. Camisoles are exclusively women's wear so they tend to be made of finer material and have different styles of necklines, but there is a lot of variation in this regard. Also, tank tops generally fit snugly to the body whereas camisoles can have a looser fit, especially the ones made for use as outerwear.
