Pregnant Amy Duggar chose a very special outfit to wear during her recent maternity photoshoot that made her late grandmother a part of the special day.

The reality star, who is currently expecting her first child with husband Dillon King, revealed via social that she chose to wear a dress her grandmother, Mary Duggar, had bought for her only months before her untimely passing.

“This dress has special meaning,” she wrote to her followers. “My [grandma] and I went shopping in June. We found this beautiful dress… but decided it was a little pricey, so I told her, ‘Let’s wait on it!’ My mom and [grandma] came over the next night for dinner and yep you guessed it, she had bought me that dress! I was so surprised!” How sweet!

She added that she wasn’t sure if she would be able to wear the dress at all, since it’s technically not a maternity dress. “I looked at the tag… and realized she bought me an XS!!!” she wrote. “Y’all, I squeezed, wiggled my way into this thing! 7 months pregnant and I’m darn proud of it! Haha! I just love the fact that even though she is no longer with us I have so many memories of her.”

Amy went on to explain what a difficult time it’s been since her grandmother’s death, explaining, “June was devastating, July was hard.” On June 9th, it was reported that 78-year old Mary Duggar had died of an accidental drowning.

County Coroner Roger W. Morris told People, “Duggar slipped and fell into the pool and drowned. Her daughter Deanna discovered her body and alerted authorities, who pronounced her dead at the scene.” Since the fateful day, the large Duggar clan has been paying tribute to their beloved grandma online, calling her “feisty” and “incredible. The news came only a month after Amy had announced her pregnancy online.

“Grandma Duggar has had two strokes over the last year and some other medical issues and it’s our understanding that Grandma Duggar had slipped and fallen and passed by the time her daughter found her in the pool,” a representative for the Duggar family told Us Weekly several days after the incident.
