I did a Skims activewear haul to see if it turned my ‘pancake booty’ into an ‘hourglass shape’ – or if it flopped

) posted a to test the A-lister's new exercise collection in the gym.

Keltie started by admitting she was a huge fan of Skims for the comfort and shaping abilities of the pieces.

"There's a couple of things I love in life. One: workout wear. Two: Skims," she proclaimed.

The excited shopper immediately purchased the $118 in a small and the matching $78 in a small.

She asked: "Will these leggings help me trick the internet into thinking I had a BBL while simultaneously surviving all my workouts?"

Keltie ripped open the packaged items as soon as they arrived.

She was a bit confused why Skims only sold a tank top and not a sports bra because they're an "underwear brand."

Before Keltie put the pieces on her body, she noticed the material's soft, "silky" feeling but didn't like the fixed seam on the top.

"I better put this on, and my two-by-four body, pancake booty better become an hourglass figure and cake," she said.

Keltie wished she got the set in an extra-small, even though she usually sizes up.

She said: "I'm very disappointed in this. I had such high hopes because that's Kim's whole thing: sculpting and lifting. Thought this would like lift my butt.

"I can't even do the butt thing."

With other workout legging brands, Keltie can give herself a wedgie to make her butt appear bigger.

She went to the gym to test the apparel during her exercise regimen.

The former big-boobed woman said if she had a larger chest, she wouldn't have to worry about her girls popping out while she's active.

However, when she squatted in the leggings, Keltie had to pull them up.

"I thought Skims would be iconic in like your waist would hold because that's her whole thing."

Still, Keltie deemed them suitable for weightlifting.

Viewers showed skepticism after watching Keltie perform in the activewear.

"I don't know, I just feel like for $195, the quality needs to be AMAZING," one honest individual remarked.

Another critic wrote: "Omg, I was going to get them to review, and they just sound so bad that I’m not even going to bother!"
