In fact, TOWIE star Lydia chose to unveil her new range at an event very close to the couple's hearts - the polo!
Reality TV star and designer Lydia, 25, looked sophisticated in an ivory lace Sweetheart Midi Dress from her own range - "one of my favourite designs" - worn with a white sleeveless jacket and matching clutch.
She even managed to look elegant walking on the mud in nude heels!
Meanwhile, Arg looked svelte in a maroon suit with white shirt... Both looked healthy and tanned after recently returning from filming ITVBe show The Only Way Is Essex in Marbella.
As guests included Lydia's mum Debbie, Denise Van Outen and Josie Gibson travelled to the SIMEC Polo at Celtic Manor Resort in Newport for the event, Lydia was a flurry of excitement and nerves.
She tweeted: "Good morning Wales. I can hardly contain my excitement for my fashion show and launch of my Lydia Rose Bright SS15 collection today @thecelticmanor."
She also explained why she chose to showcase her collection at the polo, explaining: "It seemed the perfect idea to launch my SS15 collection, the same way I met the love of my life, seven years ago. At a Polo event! All good things happen at the Polo."
In another post, Lydia described Arg as her "rock".
He, in turn, paid tribute to his long-term girlfriend with the message: "Words can't describe how proud I am of my @LydiaRoseBright Here's her Spring/summer collection http://www.lydiarosebright.com."
The event was a sell-out with more than 2,5000 guests who drank plenty of Pimm's and champagne, before enjoying a three-course lunch and afternoon tea in a huge marquee.
Speaking at the event, a thrilled Lydia said: "It was so much fun to unveil my new summer collection to thousands of people at Polo at the Manor at the Celtic Manor resort.
"The crowds have been absolutely amazing and it's incredible to see the polo up so close. Me and James actually met at a polo event seven years ago, so it wonderful to have him by my side today to cheer me on."
