Brittany Mahomes

Mahomes, a Februrary 2026 digital cover model, has been attending many NFL star weddings lately. Following Taylor Swift and Travis Kelce’s nuptials over the Fourth of July holiday weekend, Mahomes and her Kansas City Chiefs quarterback hubby, Patrick, attended Juju Smith-Schuster’s ceremony. For the July 10 event in Orange County, Calif., Mahomes stunned in a gorgeous coral Silvia Tcherassi gown paired with pink Aquazzura heels and a satin fuchsia clutch by Saint Laurent.

Olivia Culpo

Culpo, who landed the 2020 SI Swimsuit Issue cover following her photo shoot in Bali, provided the best blueprint for a black tie event. For a friend’s ceremony recently, she opted for a gauzy black floor length gown with lots of movement. The soon-to-be mom of two also donned a pink ARAKII high-low dress with matching pumps for another portion of the celebration.

How to model her look: Black is anything but basic, and a flowy dress makes for a great photo op.

Simone Biles

Biles, who was just one of the many SI Swimsuit stars who attended the aforementioned union between Swift and Kelce, dropped jaws in a maroon gown by designer Do Long, which featured an ornate tulle train.

How to model her look: Don’t be afraid of drama—in the fashion department, that is.

Katie Austin

Continuing to make a baby bump look chic wherever she goes, Austin wore a strapless blue dress to a wedding in Rhode Island earlier this summer. She kept her accessories simple and opted for a pair of gold hoops and carried a clutch in one hand.
