Floyd Mayweather's recent match against Canelo Alvarez drew the likes of not only celebrities but also five of his alleged girlfriends.

The 36-year-old boxer, who remains undefeated after he beat Alvarez and won through a decision and controversial draw, reportedly outfitted his five girlfriends in outfits by the same fashion designer. (Mayweather beat Alvarez in a match on Saturday, Sept. 14 in Las Vegas at the MGM Grand Garden Arena.)

Media Takeout reported on Monday that his five girlfriends all wore custom dresses and outfits by fashion designer Michael Costello.

The designer, however, refused to deny or confirm the claim. Instead, he posted a statement on Instagram stating that he will not address the report out of respect for Mayweather.

"Due to respect of our clients we @michaelcostello31 & #mtcostello will not be responding to any media questions about Floyd Mayweather, his family and friends," Costello wrote. "Please respect our privacy and theirs. We cannot control who makes purchases online Thank you."

Costello is a fashion designer who competed on Project Runway season 8 and finished in 4th place before he was eliminated. He later appeared on Project Runway All-Stars season 1. He showed his upcoming Spring 2014 collection at Mercedez Benz Fashion week earlier this month, according to his website.

After extensive research, Enstars learned the only one of Mayweather's rumored girlfriends wore a custom gown on Saturday by Costello. Queen Princess Love, the former model who called herself Mayweather's number one girlfriend earlier this month, wrote on Instagram: "Special thanks to @michaelcostello31 @valeriecostello8 @mtcostello for my beautiful custom made gown."

Another one of Mayweather's alleged girlfriends, Jessi Lee wrote a thank you note on the social media site to Magnum Opus 360, another company.

"Thank u so much @magnumopus360 for helping me with my entire outfit last night," she wrote on her Instagram. "Everything was put together so well! @hairbyxtina rocked my hair and @makeupari did a amazing job on my makeup."

Mayweather's ex-fiancee, Shantel Jackson shared photos of herself before and after the fight. She captioned the picture of herself near the boxing ring, "Amazing night... Amazing fight... #murdered #slayed #theone #allsmiles #limitededition."

Rapper Lil Kim--whom Mayweather himself revealed to have went on a luxury shopping spree for on her birthday in July--captioned a video of herself at his afterparty Saturday night with P.Diddy and Meek Mill on Instagram.

"Shouting out my BFF @floydmayweather with @iamdiddy @meekmill #tmt 4 life!!!" she captioned the video.

Mayweather sparked the rumors that he has at least six girlfriends when she shared a collage featuring the five beautiful women in a thank you post on Instagram last month.

"I really want to thank these ladies for supporting and helping me everyday throughout this training..."
