Isaac Plath Shares Photos from 'Amazing' Homecoming as Sister Lydia Glows That He Looks 'Quite Spiffy'

The youngest boy in the 'Welcome to Plathville' family shared several sweet photos on Instagram from the high school dance

Isaac Plath got all spruced up as he attended a milestone high school event.

The Welcome to Plathville star, 17, shared a series of sweet photos from his homecoming dance on Instagram Monday, posing with several friends, a large group of high schoolers and a girl that was likely his date to the dance.

“Homecoming!!” he wrote in the caption, adding that he “had an amazing time.”

His dressy look — a suit jacket and pants with a white dress shirt underneath and a gold bow tie — caught the attention of older sister Lydia Plath, who complimented her sibling’s style.

“Someone looks quite spiffy!😁,” Lydia, 19, commented on Isaac’s post.

Social media is still relatively new to the siblings, who joined Instagram less than two years ago. Their older sister Moriah, as well as two of their older brothers — Micah, 22, and Ethan, 25 — are both active on Instagram, but none of their other family members use social media.

The 11 members of the Plath family gained fame for their TLC show, which premiered in 2019 and continues to trace the challenges the children face as a result of Barry and Kim’s strict conservative values.

In hopes of instilling their traditional values and beliefs, they’ve chosen to limit their children's exposure to modern technology.

"We have limited technology," Kim previously explained. "We have limited computers. They don't play any video games. They never have."

While Isaac may be free to use social media now, the Plath family is still juggling some major challenges.

In 2022, Kim and Barry split up after nearly two and a half decades of marriage, telling PEOPLE in a joint statement that although it was “not an easy decision, we know it's the best choice for both of us.”

They continued, “We have been through many highs and lows in our 24 years of marriage and as we navigate this new chapter in our lives, we will co-parent our amazing children.”

Season 5 of the TLC show premiered last month and has chronicled the shifting family dynamics, particularly concerning oldest child Ethan and his wife, Olivia, who is largely estranged from the family.

Olivia, 25, and Kim are not on speaking terms, and Moriah also hit a breaking point in season 4 when Olivia refused to attend a birthday party due to Kim’s presence at the event.

Tensions grew further after Olivia accused Kim of using her husband’s credit card in a confessional in season 4, which prompted Moriah, Micah, Lydia and Isaac to release a joint statement in defense of their mother. During the season 5 premiere, Olivia found herself on the outs as none of Ethan’s siblings would talk to her.

The tensions, on top of her parents divorce, pushed Moriah to a “dark” place, she admitted to her father during a recent episode.

She confessed that at one point she "didn't want to live anymore," adding, "A few months ago I hit rock bottom. I got used to just being miserable and I forgot what it felt like to be happy. And I was just yucky on the inside. I was very dark, very depressed.”
