Sideboob -- that's like so five minutes ago! It's sidebum that's become one of the biggest trends in fashion. The style, which shows just a flash of skin or of the butt cheek, has been on the rise for over a year now.
While it might seem as though sideboob is super scandalous, since it shows off a little too much and can lead to a nip slip, sidebum is even more terrifying, since it pretty much requires the wearer to go commando aka sans undies, since you can't really have pantylines with sidebum. And we all know what happens when said starlet gets out of a car!
Still, it remains a dangerous fashion "do."
Also, sidebum comes in all shapes, sizes and lengths. It can be just a hint, a slit, or a sexy flash of skin, covered by fabric. Or it can be a full on butt-baring look, where the air hits the flesh. The sidebum look often incorporates the thigh and the length of the leg, too.
There are so many varieties of sidebum! We've seen 'em all! The one constant is that sidebum shows off the shapely, round and curvaceous derriere in several sexified ways.

And in Antonio Berardi, which is much racier. What shapely stems (and bootay) you have, Gwynnie!

Taylor Swift doesn't always show skin, but this is subtle sidebum.
Upon closer inspection...it's more like an optical illusion created by two-toned fabric. It still counts.
