Jack Flaherty’s girlfriend Katie Johnson’s DIY silver studded red bikini look fuels brand new business venture

Detroit Tigers pitcher Jack Flaherty's girlfriend, Katie Johnson, launched her new business venture, a bikini brand called "YourKini by Katie." The brand involves different designs of swimwear, curated by Johnson herself.

On Monday, Katie shared a sun-soaked clip of herself wearing a DIY silver-studded red bikini. She revealed that the swimwear was designed and customized by her personally. In the video, Johnson is enjoying the shoreline in a red bikini with evenly spaced silver studs. She captioned the reel:

"So happy to finally say... YourKini by Katie is now open for bookings ✨ Each piece is thoughtfully made, one of a kind, and designed by you. I can't wait to create something special for you ✨"

Since retirement, the USC alum has turned into a Pilates instructor and often shares fitness and lifestyle content on social media.

Jack Flaherty shares cozy midseason moments with Katie Johnson

In September, Jack Flaherty took a break from the regular season to spend quality downtime with his girlfriend, Katie Johnson. He shared several black-and-white snapshots in which the couple got cozy with each other.

He also shared a snippet from a book or online material, which suggests that the diamonds are made after intense pressure is applied. She shared a photo of Johnson sitting on top of the Tigers' dugout with fireworks behind her. It might be after a win.

"diamonds make pressure," Flaherty captioned the post.

Johnson and the Tigers pitcher went public with their relationship earlier this year. They shared photos from a dinner date at The French Laundry in California, confirming the dating rumors.

Johnson was previously engaged to NBA player Trey Lyles.
