"Got the shoes to match ☁️," she captioned the carousel of sassy snapshots.

In one image, Graham wore a tight tie-dye cover-up to bring the ensemble together while popping her left knee and tilting her hat over her eyes.

Graham opened up to PEOPLE earlier this month about expecting her second child, saying that being in control "just gets thrown out the window" during pregnancy, something she learned her first go-around.

"I learned that the hard way when I tried to control everything when I was pregnant with Isaac and I told myself that I was going to bounce right back because I was breastfeeding and everybody told me, 'Oh, if you breastfeed you're going to lose all the weight,' " she said. "And I had a few honest women tell me you will never feel the same. So they were just blunt with me and sure enough, I haven't felt the same."

"And then boom. I was like, 'Well, I just got pregnant again so maybe I'll never feel the same and I don't even know what I felt like before I was pregnant with Isaac anyways,' " she added.
