Joy-Anna Duggar seemingly followed her older sister, Jinger Duggar, in breaking their dad's strict dress code by posting a snap of her rocking a sexy outfit.

The "Counting On" alum has noticeably made a shift in her fashion style. She recently flaunted her curves by sharing a mirror selfie on her Instagram Story, rocking an outfit unexpected from her conservative family.

The Sun captured a screenshot of Joy-Anna's post. In the photo, she wore a low-cut white V-neck shirt with a green blazer. She paired it with tight, light-colored denim jeans.

It wasn't the first time she wore jeans. In a video she shared earlier this month, she was noticeably wearing pants while hanging her family pictures on the wall with her husband, Austin Forsyth. Also, she has lots of pictures on Instagram of her rocking pants.

Jim Bob and his wife, Michelle, raised their children under a strict dress code. The girls are required to dress modestly in skirts and dresses that cover their shoulders and knees.

Joy-Anna spoke about her wardrobe change when she answered her fans' questions earlier this year on her YouTube channel. According to her, she discovered that there was nothing in the Bible supporting her parents' specific guidelines where girls are expected to wear loose-fitting dresses and long skirts instead of jeans.

"I'd always worn skirts my whole life, and so for me, I wasn't in a rush," she said. "So really, the last year we really prayed about it and felt like there wasn't anything in scripture - there isn't anything in scripture that's black and white on dress. It talks a lot about modesty, but I feel like you can be modest and wear pants, and so that's kind of where we came to."

Jinger is the first Duggar to break their dad's dress code. She changed her wardrobe after she moved to Los Angeles with her husband, Jeremy Vuolo. The TLC star has been spotted wearing sleeveless tops, jeans and shorts.

In her memoir "Becoming Free Indeed," Jinger detailed how she walked away from the Institute in Basic Life Principles (IBLP)in 2017. IBLP is an organization established by disgraced minister Bill Gothard in 1961, and her parents are devout followers.

"I thought I had to wear only skirts and dresses to please God," Jinger, 29, told People in January. "And if I step outside of what I think is expected of me, I would think God's going to be so displeased with me, and it could bring harm on myself."

Jinger said she spoke with her parents when she started wearing pants, and she let them know what she saw in the Bible. It was reportedly years of discussion.

"I understand we can be in totally different places and come to different conclusions, and at the end of the day, they will go on their journey, and I'm on mine, and each of us can arrive in different places at different times. We've just sought to talk about those things and, at times, just agree to disagree," Jinger added.
