The brunette beauty was joined by family and close friends, including Pippa O'Connor, as she tied the knot in the four-star surrounds of Carton House, County Kildare.
The stunning bride wore an elegant, slim-fitting white gown with silver embroidered cap sleeves, a medium-scooped back and eye-catching silver twist at the waist.
She's one of the country's biggest make-up artists but Tara chose not to take care of her own beauty look on the big day, instead entrusting those duties to Paula Callan of luxurious Dublin salon, Callan and Co..
The overjoyed newlywed took to Instagram to share photos of the ceremony, including a photo of the moment she walked down the aisle with her father, which she captioned: "We laughed the whole way down the aisle."
She also took time out to thank friends and followers for their well-wishes with a social media post which hinted at her ecstatic mood.
"I am completely overcome with love and emotion," she wrote on Instagram.
"I can't put into words how happy I feel and how lucky I am! Thank you so much your lovely comments and kind wishes. You have all made me feel very special."
Tara also provided friends with some cake inspiration by posting a photo of the wedding's sweet treats.
Her cake was created by award-winning, Dublin-based bakers The Cakecuppery and featured a cake table complete with cupcakes, cake pops and an intricately-designed, three-tier wedding cake.
Last year, the Andrea Roche-model revealed that choosing the right dress wasn't as easy as she had anticipated.
"Things didn't happen the way I thought they would, I was dreading looking for a dress because I don't wear dresses unless I'm modelling," the make-up artist told the Diary
"I thought they'd all look really stupid on me but then I loved the second one I tried on, so I stopped looking after that.
"I'm doing make-up at a few weddings a week at the moment and when the bride comes out I'm like 'I want your dress' so hopefully I'll still love my one by next August."
