Donning a Liancarlo dress, Jamie Lynn shone in a stunning fishtail gown which featured floral lace detailing and a V-cut neck. Britney's little sister completed her bridal look with a dramatic cascading veil, which she pinned onto her elegant up-do.

The 22-year-old decided to have her blonde locks scooped into an elegant chignon for the ceremony, but wore her waves loose for the reception. She accessorised with silver and pearl drop earrings and kept her look natural with barely-there Make Up.
The blushing bride, who wed her long-term boyfriend Jamie Watson in a Louisiana ceremony last week, was snapped in a photo by I Do Bridal Couture – the boutique she bought her dress from. The shop owners were invited to the reception and eagerly posed with the newlywed.
"It's official ya'll! @jamielynnspears is now Mrs. James Watson!" they wrote next to a photo. "We are so happy to have been part of this celebration of love. The beautiful bride, Mrs. Lynne and sweet Maddie all wore custom gowns by @liancarlodesign. More pics to come! Xo."
Jamie Lynn didn't seem to mind that her mother also wore a strikingly similar ivory Liancarlo dress.

The bride's five-year-old daughter Maddie also matched wearing the same designer, and like Jamie Lynn held a bouquet of pastel coloured roses for the ceremony. Jamie Lynn gave birth to Maddie when she was 16 years old and going out with her high school boyfriend and former fiancé Casey Aldridge.
In the lead-up to the big day, the bridal boutique posted another photo.
"We had a very special bride today," they wrote. "We are so thrilled to welcome the sweet and talented @jamielynnspears to the I Do family! She choose a stunning @liancarlodesign gown. We can't wait for the big day! Xo."
Jamie Lynn and her 31-year-old husband Jamie tied the knot at the tea room at Audubon Tea Room in New Orleans.
