Brittany Mahomes, Olivia Culpo and Claire Kittle wear matching jersey number necklaces at Super Bowl 2024

Olivia Culpo showed off her custom “23” necklace in honor of fiancé Christian McCaffrey.

They’re jersey girls of a different kind.

As the San Francisco 49ers and the Kansas City Chiefs battle it out on the field during Super Bowl 2024, fans less interested in the football game are turning their eyes to the sidelines to check out the WAGs’ style.

And what better way to show love than by wearing a blinged-out number necklace to pay homage to your beau’s jersey? Brittany Mahomes, Olivia Culpo and Claire Kittle all had the same idea for the Feb. 11 game, sporting matching pendants by Simon G Jewelry.

The trio all wore personalized versions of a diamond-covered design that retails for $1,870, a representative for the brand confirms to Page Six Style.

Mahomes paired her “15” necklace with another special piece featuring husband Patrick’s name alongside those of their two children: Sterling, 2, and Bronze, 1.

She further repped the Chiefs quarterback with her customized red corset jumpsuit from BroDenim, while the toddlers cheered on their dad in custom denim looks by the brand.

Culpo teamed her “23” necklace with a Frankie Shop trench coat customized by BroDenim with fiancé Christian McCaffrey’s number and name, which she layered over a black catsuit and further accessorized with an Hermès Kelly purse.

Kittle — whose husband, George Kittle, is on the 49ers with McCaffrey — rocked her dainty “85” necklace to parties in Las Vegas ahead of the big game. And on Sunday, she went even bigger with her bling, wearing an all-silver look with a huge “85” chain, “8” and “5” earrings and a silver signet ring etched with her spouse’s number.

Fans can get their own versions of these WAG-worthy baubles, as Simon G’s custom initial necklaces start at $1,150.

Mahomes, Kittle and Culpo weren’t the only ones repping their men at Allegiant Stadium; Taylor Swift wore a jersey-inspired necklace of her own, sporting an “87” diamond pendant in honor of boyfriend Travis Kelce.

The “Bejeweled” singer picked a custom Stephanie Gottlieb necklace ($4,250) and a glittering Judith Leiber football clutch ($4,495) featuring the same digits.

When it comes to meaningful jewelry, nobody does it like Swift; she’s shown off countless sartorial nods to Kelce throughout the season, from blinged-out friendship bracelets to vintage Chiefs merch.

Stay tuned to see which team comes home with the biggest piece of jewelry: the Super Bowl championship ring.
