McKayla Maroney kept it racy on Halloween.

McKayla Maroney Flaunts Her Chest In Previous Instagram Selfie

Over the weekend, the Olympic gymnast added photos of her costume where she went as a "dog on acid." But she wrote in the caption that everyone thought she was a bunny.

This is probably an honest mistake since Maroney wore long ears although her colorful top added a trippy effect. In fact, her top was super low-cut as she let some chest skin show.

McKayla Maroney Sticks Out Her Tongue On Instagram

Overall, it looks like the gymnast had a great Halloween as she showed off her colorful makeup and little dog collar.

Sadly though, Maroney got pretty bummed out that Halloween had to end yet again this year. In another photo, she pointed out that she feels post-Halloween depression as she kept part of her costume on.

In a previous snapshot, Maroney mentioned that one of her costume options was going to be a "PG13 gymnast." This made sense as she wore a white one-piece outfit that bared her long and slender legs.
