Britney Spears' Daisy Dukes are all caught up in the wind and the 39-year-old is all legs as a result. On Sunday night, Britney's 29-year-old sister Jamie Lynn Spears uploaded a huge batch of unearthed throwbacks featuring "Toxic" sister Britney, all for International Women's Day and even including the siblings' mom Lynne Spears. Jamie Lynn, followed by 2.1 million on Instagram, also took to her stories, where a rare street throwback of herself and Grammy winner Britney brought out old-school '90s vibes, plus Britney's famous legs.

Scroll for the photo. The above one formed part of the "PHOTO DUMP" marking International Women's Day as Netflix star Jamie Lynn shared her 2014 wedding and Britney in a fishtail dress all bridesmaid and zipping her sister up.

Definitely not in formal dresses, but still together, was this photo, one showing Britney, Jamie Lynn, and what was likely their mother crossing a city street, with Jamie Lynn still a pre-teen. Britney was in the center, and those Daisy Dukes were likely all fans could talk about.

While Jamie Lynn went skimpy in a pattern blue tank top and matching miniskirt, Britney was upping the ante in shredded and frayed Daisy Dukes and flip-flops, channeling the signature old-school Britney wardrobe as she wore a crop top and multicolor sweater around her shoulders, plus a tan handbag and shades.

"#internationalwomensday," Jamie Lynn wrote, then throwing out her sister's name via her Instagram handle. Jamie Lynn then posted photos of famous and inspiring women including Tina Fey and Billie Eilish.

Jamie Lynn has been shouting out Britney with more than just yesterday's throwbacks. The "Sweet Magnolias" actress has been backing her sister amid The New York Times-released "Framing Britney Spears" documentary, taking to social media and writing:

"Everyone you meet is fighting a battle you know nothing about. Be kind. Always," also adding: "Dear media, try not to repeat the mistakes of your past. Look where that got us. Do better." Spears also finds herself supported by 27-year-old boyfriend Sam Asghari. See Jamie Lynn's legs rivaling Britney's below and click here for the photo.

Jamie Lynn is fresh from making major bikini headlines – scroll for the video – as she stripped down to two stringy two-pieces this year and even talked about her "stretch marks." Admitting she was "nervous" about posting the jaw-dropping footage, the mom to Maddie and Ivey wrote:

"I'm always preaching to my girls about being confident, and to apologize for being a strong woman, so I think it's important to practice what I preach... stretch marks and all."
