When country singer Jerrod Niemann wed longtime girlfriend Morgan Petek high atop Puerto Rico’s historic fort Castillo de San Cristébal in October, he was (obviously!) in awe of his bride’s beauty.

But, like most grooms, Niemann, 35, was totally clueless about the stress and struggle that went into Petek’s search for the perfect wedding gown.

Luckily, Petek’s journey to find the dress that made her feel “like an absolute princess” was documented on TLC’s Say Yes to the Dress: Atlanta for her groom – and all of us – to see. And there were definitely some (super curve-hugging!) hiccups along the way.

“I tried on a dress, and said yes to a large portion of it,” Petek, 33, tells PEOPLE of her Lazaro design. However, saying yes to the whole thing wasn’t as easy as it is for some brides.
