All the single ladies: Put your hands up and show Beyoncé some love for looking so smoking hot just 10 weeks after giving birth to her baby girl, Blue Ivy.

After multiple sightings of the star out and about in NYC since she first emerged at a Jay-Z's post-Carnegie Hall party, the singer got all dolled up to hang out with first lady Michelle Obama in Manhattan on Monday night.

The first lady of hip-hop and the actual first lady gathered at the Greenwich Hotel for a fundraising event for President Obama. Along with raising some dough, Beyoncé also raised eyebrows, thanks to her slamming post-baby body. Decked out in a body-hugging navy dress by Victoria Beckham, B rocked sky-high heels, dazzling bling (including a diamond-encrusted eagle) and her hair pulled back in a simple ponytail. So what was Beyoncé doing right in terms of styling herself as a new mom?

"When you think of all the things women dislike about themselves, the majority don't like their upper arms and also have skirt-length issues, so she's addressed both of these. It's an interesting choice because it's snug, not tight," celebrity stylist Robert Verdi told MTV News about B's post-baby style. "There's a distinction. It's body-flattering, for sure.

"It's also a very tasteful length: 2 inches above the knee. It's also a very conservative color, and it's very covered, but it still remains very sexy," he continued about the look. "You don't see all the bumps that women have post-pregnancy. ... Again, the distinction is it's body-conscious without revealing every lump and bump. Tight ain't right, but this ain't tight. This is body-skimming."

With Beyoncé heading back into the spotlight more and more, including a set of shows planned for Memorial Day weekend, does Verdi think Queen B will reassess her stage style now that she's a mom?

"I don't think we've seen the last of Beyoncé's crotch," he joked about Beyoncé's love for leotards. "She's really young, and ... her equity is in her sex appeal, so you can't dismiss that. She's not going to cover up. I think you've seen a similar evolution with Madonna, where fashion is sexy but is more intellectual. It's not as in-your-face. I think you're going to see the same thing with her. You evolve, but I don't think you stop being an attractive woman because you've had a child."
