The 31-year-old singer also used the video to convey a message of body positivity to her fanbase, writing, "How much do you think I weigh? No one's business."

"Cause I'm a bad b--- no matter what my weight. But let's normalize 165 lbs," she added.

Her capsule collection includes bras, panties, bustiers, corsets, and bodysuits with sizes ranging from sizes 30A to 46DDD and XS to 4X and prices starting at $49.99.

"I just wanted to feel good and be comfortable as well as looking hot," she explained. "It all comes from within and it's all about what makes you feel good. That's what shines. You could be wearing the hottest outfits and if you don't feel good in it, what's the point?"

In a previous interview with Fox News, Rexha discussed the apparent double standard of women embracing their sexuality compared to men, declaring she's proud to be sexy.

"If I want to be sexy, I’m going to be sexy," the singer said.

"If a man were to take off his shirt and show off his abs and rub oil all over his body, I doubt anyone would say that he’s exploiting his sexuality — and that pisses me off. So, I’m definitely going to do what I want and do what I feel."
