After saying "yes" to Ben Seewald's marriage proposal, Jessa Duggar, the star of TLC's hit reality show 19 Kids & Counting (airing Tuesdays at 9 p.m.), tells PEOPLE exclusively the two have their wedding plans set.
"I am super excited," Jessa says. "Everybody has really been pitching in."
Jessa, 21, and Ben, 19, will share wedding vows and their very first kiss on Nov. 1 and have already sent out invitations, picked their colors and bridal party, and have all the bridesmaids' dresses on hand. Most important? Jessa has already picked out her wedding dress.
"I put it on, looked in the mirror, and it hit me," Jessa says. "I'm going to be a bride."
Jessa's parents, Jim Bob, 49, and Michelle, 47, have helped with the couple's wedding plans and are getting excited for the upcoming nuptials.
"I tell you it is very busy," Jim Bob says. "Jessa is working on all these details that she and Ben are planning. I really don't have a vision of how to put a wedding together, it is just an endless amount of details and choices. It is overwhelming. But, we are excited for Ben and Jessa and how the Lord has worked in their lives."
For Michelle, watching a second daughter get ready to head down the aisle has been emotional. Daughter Jill, 23, married Derick Dillard, 25 on June 21, and revealed her pregnancy to PEOPLE weeks afterward. This year's 19 Kids & Counting season features her wedding plans, including this exclusive sneak peek of tonight's episode, airing at 9 p.m. ET, of Jill trying on wedding dresses.
"We are enjoying spending the time with Jessa and Ben now," Michelle says. "She'll be doing her own thing and having her own family before long. I realize that all our lives are going to change when she gets married, and I tell her younger siblings that it will be fun in a new way."
