"10yrs later and it still, (sorta), fits," she captioned the photo carousel, featuring one pic of herself smiling and modeling her red Versace dress at home, alongside a photo of herself wearing it on the 2011 Golden Globes red carpet.
Jones made headlines for her bombshell look 10 years ago when she donned the flaming red Versace gown with a plunging neckline and bold cutouts on the side.
The former Mad Men actress has been nominated for two Golden Globes for her role as Betty Draper. This year, she doesn't have a project that's nominated, but she's still taking part in the festivities.
Jones shared more photos in her Instagram Stories calling the gown her "dream dress."
She also shared a photo wearing the high-fashion design while holding up a pink frosted donut, writing: "Part of the problem. Also I had a child." (Jones' son, Xander Dane, is now 9 years old.)

Her try-on session inspired her Mad Men co-star (and on-screen daughter) Kiernan Shipka to take part as well.
The 21-year-old actress shared a photo of her and Jones at the 2011 ceremony, and decided to rewear the outfit she donned that night, posing in the velvet babydoll dress with white lace collar while sitting in her backyard.
"hey @januaryjones I heard we're putting on our Golden Globes looks from 10 years ago," Shipka captioned the sweet post.
