I would qualify this dress as a "stay inside dress", because it's comfortable enough to be raised to the ranks of PJs. And yes, PJ ranks are above the others. I believe it goes: pyjamas, sweatpants, leggings, jeans, pleated pants, wedding dress.

This is a short dress with plongeant V neckline, heavy stretch fabric, short sleeves, slight balloon skirt and wide elastic waist band.

Composition: 92% Rayon, 8% Spandex
