The final look revealed on Thursday was a custom Atelier Versace wedding dress. Crafted in a delicate white silk cady, the design featured a portrait neckline that wrapped around the shoulders and came together with a stream of pearl buttons. The seamline of the bodice followed the corset boning that narrowed at the waist.
The column silhouette was cut with a front leg-slit, while the back pleats from the waist cascaded into a three-meter train. Spears' veil was crafted from four and a half meters of silk tulle trimmed in silk satin. The look was completed with tulle gloves embellished with pearls and matching white satin pumps. The gown was handsewn by the tailors of Atelier Versace for over 700 hours.
For his wedding look, Asghari sported a custom Atelier Versace tuxedo. The black wool tuxedo featured a double-breasted peak lapel jacket with silk satin details, and pants with a banded belt at the waist. A white shirt with traditional smoking collar was paired with a matching black, silk bow tie. The look was completed with black loafers.
To complete Spears' look, Sofia Tilbury brought aunt Charlotte Tilbury's rose petal pink makeup design to life and Spears sported her signature blonde hair cascading down around her face and back.
As for accessories, Spears donned diamonds by jeweler Stephanie Gottlieb. In an interview with ET, Gottlieb revealed that, in addition to her wedding band, Spears wore a bracelet during the nuptials, and had a total of 62 carats of diamonds on during her big day.
Gottlieb added that Spears' bands are two carats each, and that Asghari had two classic platinum bands. Neither the bride nor groom had an inscription on their bands, Gottlieb said.
According to Vogue, the bride enjoyed several outfit changes after the ceremony, including black and red mini dresses also designed by Versace.
"We wanted to create a glowing look that complemented and enhanced Britney’s custom Versace gowns -- she had four exquisite dresses, all designed by Donatella Versace," Sofia Tilbury exclusively told ET of the bride's glam. "We created a dreamy day-to-night makeup look for Britney that enhanced her natural beauty and worked with her dress changes -- a soft smokey eye, beautifully radiant skin, peachy love-blushed cheeks and the perfect nude-pink lip! It took her from her timeless, classic long white silk ceremony dress right through to her sexy after-party dresses!"
After getting all dressed up and exchanging vows, the newlyweds celebrated with celebrity guests like Paris and Kathy Hilton, Versace herself, Selena Gomez, Drew Barrymore and Spears' longtime friend and collaborator, Madonna.
However, most of Spears' immediate family was not present, including her estranged parents and sister Jamie Lynn Spears -- who, according to a source, were not invited. Her sons with ex Kevin Federline also did not attend.
"Although the boys will not be in attendance, Kevin and the boys are happy for Britney and wish her and Sam all the best going forward," Mark Vincent Kaplan, Federline's attorney, previously told ET. "They are excited that this will be a positive development for her post-conservatorship life."
"Kevin and the boys want her to be happy," Kaplan added. "Hopefully this will be a key for her to be happy and remain happy going forward. They all feel that this is Britney and Sam's day and nothing should take away from that."
