This weekend was a busy one for model Ashley Graham, as she attended the wedding of her little sister and rocked a super chic—though atypical for your average "I do" ceremony—look.

Abigail Graham—who calls herself a "combination of Leslie Knope, Captain Kirk, and Rosie the Riveter" on Instagram—is seen in a photo with her big sister in which the new America's Next Top Model judge sends her congratulations and gives us a look at both of their outfits.

In another photo that also features the bearded groom, we get details about who designed the bride's dress—as well as Ashley's super sexy look. "Abby's dress is from a local Lincoln, NE boutique Ellynne Bridal, size 18/20," the 20-something superstar wrote. "Looking Ah-MAZING."

In the snapshot, the off-duty supermodel—with her hair up in a high ponytail—tags herself showing that the leather pants are from Rag & Bone and the jacket is from Adrienne Landau. (In a separate video, Ashley also dons a Rag & Bone jacket with her name across on the back.)

While we think Ashley looks incredible (as usual!), her non-traditional wedding attire did catch some negative attention on Instagram. Abigail rushed to her sister's rescue, writing, "I asked my sister to wear that sexy outfit, and I asked my sister to post that photo because her ass looks so good. SO GOOD."

Don't mess with the Graham sisters, you guys.
