Acronyms can be scary.

SARS. GMAT. ASAP.

But the most threatening — and pervasive — of them? Those dreaded underthing-related ones.

VBL: visible bra lines.

FBF: false back fat. A condition created by too-tight bras that cause unseemly ripples and lumps.

UBSR: uniboob sports rack. A situation commonly brought on by the sports bra.

Leading the fight against such evils: Sassybax, seamless stretch bras that started out as a pair of control-top pantyhose (go figger). They come in three styles, multiple colors, and provide comfort, support, and, most importantly, a smooth, bulge-free silhouette (even when worn under ludicrously tight Lycra get-ups).

Which means you won’t find yourself pulling and shifting all day.

And you won’t have to tell anyone to MYOB.
