Sister Wives star Christine Brown's daughter Ysabel, 20, goes braless and risks wardrobe malfunction during London trip

CHRISTINE Brown's daughter Ysabel has narrowly avoided a major wardrobe malfunction while sporting a tube top in London.

The Sister Wives child star jetted to England this week with her sisters Truely and Mykelti as well as her mom Christine and her fiancé David Woolley.

But while enjoying the sights and sounds of London, Ysabel, 20, nearly suffered a major wardrobe malfunction.

The young reality star took to her Instagram profile over the weekend to share a few snaps from her short trip over the pond.

In the first photo, the TV personality posed on a city street while wearing a black crop top and jeans.

But in a second snap, Ysabel was just moments away from exposing her chest as she was caught in motion in front of the Camden Lock bridge.

The blonde kicked up her left foot and smiled brightly, showing off her cute outfit consisting of black overalls and a white tube top.

Christine and Kody's daughter paired the look with white sneakers and oversized earrings.

Ysabel wore her long blonde hair straight and sported minimal makeup for her fun exploration day.

The TV star jumped to the side while holding a beer, laughing as her top nearly slid down her front.

The 20-year-old was moments away from exposing all in the sexy snap.

Ysabel captioned her post: "A few days in London," leaving fans to flood the comments section with their compliments.

The Utah native has been enjoying her England getaway with family this week.

But just days prior to departing the States, she soft-launched her new boyfriend and fans have since demanded more information.

Sister Wives fans have watched Ysabel grow up on the TLC show, and now it appears she has a new boyfriend.

She shared a new set of photos on her Instagram that was captioned: "Celebrating gwendlyn and bea and moments between and after."

Gwendlyn is her 21-year-old sister, and Bea is Gwen's brand new spouse Beatriz Queiroz.

The couple married on July 15, and Ysabel's social media post was filled with photos from her sister's wedding week.

The first photo in the Instagram carousel was a black and white snap featuring Ysabel, one of her sister Mykelti's children, and the mystery man.

This pic was taken at Gwen's wedding celebration.

A neon sign behind them said "The Queirozes," and they were dressed to the nines.

In addition to the photo, the mystery man made two other small appearances in the photos.

His face wasn't visible, but it appeared to be him because he was wearing the same bracelet in all three pics.

In the comment section of Ysabel's post and on Reddit, fans begged the reality star to spill the details about her new man.

One asked: "Is this a soft launch?!?"

Someone else said: "Oh umm so who is the beast of a dude with that hand of yours on his thigh?"

"I love this for her!! But I do hope she doesn’t rush to get married like all her sisters so far," added a third.

Another said: "That looks like a man she has experienced some fellowship with."
