Shelley Sullivan, the 51-year-old founder of MCoBeauty, was photographed at Sydney Airport wearing the same outfit she was seen in three weeks earlier, underscoring a low-key approach to public appearances as she navigates recent personal upheaval.

Sullivan arrived at the terminal in a fitted white singlet layered under a cropped cream cardigan, slim-fit black trousers, beige sandals and an oversized beige tote slung over her shoulder. The cosmetics executive, who publicly revealed significant weight loss earlier this year, kept her makeup minimal, swept her blonde hair into a loose style and accessorised with gold jewellery while speaking on her phone.

The outfit had first been photographed when Sullivan returned from Hamilton Island last month, prompting commentary about a pared-back wardrobe rotation amid her ongoing domestic matters. Sullivan has been the subject of intense media scrutiny since her abrupt separation from husband Anthony last year.

Sources and previous reporting say the split followed a dispute that led Anthony to leave the country for the United States, while Sullivan reportedly moved into the InterContinental Hotel in Double Bay. She was later seen being comforted by her mother, Kerrie, in Sydney’s financial district. A friend previously told Daily Mail Australia that "Shelley is absolutely shattered by the split" and that she has relied on a close network of friends for support.

Anthony Sullivan is an accountant and chief executive of Quantaco, a firm providing financial services to companies in the hospitality sector. The couple, who had been friends for years before dating, were married in a ceremony in Point Piper in 2016 and have since moved out of an $11,000-a-week heritage-listed rental property in Bellevue Hill.

Shelley Sullivan established her career in the 1990s with a model and talent agency before launching her masstige beauty brand, ModelCo. The brand became known for innovations including the Tan Airbrush In A Can, which the company says was introduced more than two decades ago and remains a high-volume seller globally, and for early heated eyelash curler products. ModelCo has been represented by high-profile models and influencers and has grown to challenge established makeup lines in the Australian market.

In 2022, reporting indicates that a large Australian conglomerate acquired a stake in MCoBeauty. Sullivan’s repeating of an outfit at the airport comes as she continues to run a multimillion-dollar business while managing the fallout from her personal life. Her public appearances have combined signs of a restrained personal style with continued visibility as a commercial figure in beauty and fashion.
