The blond bombshell sported a neutral-colored ʙικιɴι by Acacia Swimwear at the beach in Miami, where she took in the sun and splashed around on shore.

McKinney, 23, donned a black coverup that didn’t actually cover much as she posed with fans and a pal in the sand and surf.

Though the model told Ocean Drive this month that her “boobs decreased in size … down one size, for sure,” it appears she still has a difficult time finding ʙικιɴι tops that can fully contain her ample curves.

After hanging out with her boyfriend, Stephen Dorff, the model stripped down and jumped into the water.

But it wasn’t all smooth sailing for 22-year-old Charlotte. She had a tough time keeping her chest covered up.

“It is bulls*** to ask about my bra size,” Charlotte, who doesn’t seem so shy about showing off, said in a recent interview. “Why do you want to know? What’s it to you? I mean are you going to buy me a bra or…? I don’t get it.”

Charlotte had to take swim breaks to make sure her ʙικιɴι bottoms stayed in place.

But that didn’t stop her from storming the beach! Do you think her ʙικιɴι was a hit or a miss? Tell us in the comments!
