A woman who says she was left at the altar and decided to wear her wedding dress to her planned hen party was left in tears after she was mocked by other racegoers at Chester Racecourse's Ladies' Day, she and the venue said.

Claire Bell, 42, of Huddersfield, told reporters she had been devastated when her fiancé ended their relationship months before their planned wedding but chose to go ahead with her prearranged hen celebration with a group of 12 friends. Bell, who is neurodivergent and has a disability, bought the Randy Fenoli "Effie Blue" dress from a TikTok shop and said she wanted to feel like a bride for the day.

Bell said the outing, which she described as intended to be empowering, became distressing when she was met with a stream of negative comments from other attendees. She recounted hearing people call her "mutton dressed as lamb, pathetic, a mouth breather, stupid, ridiculous" and said one person overheard her telling her story and said, "he had a lucky escape." She said roughly 18% of the responses she received were positive and the rest negative.

Bell also described a separate confrontation while trying to find a disabled toilet, saying a young man pointed at her and said, "you look stupid," then laughed with his companion. She said her party spent about half an hour comforting her before she left and that she felt so upset she had to take the following day off work. Bell works in education.

After the incident she posted about the episode on TikTok, where she said she received thousands of supportive comments and messages, and that Chester Races and others had offered supportive responses and gifts. "I've had people disgusted with what happened – the positive will outshine this, but at the moment I'm traumatised and ill," she said.

Chester Racecourse issued a statement saying it was "disappointed to hear of this guest's experience" and that it was "passionate about ensuring every guest enjoys their time with us and that their individual needs are catered for." The venue added that it invests in facilities across the site, including a plentiful supply of toilets, and that it was liaising directly with the guest "to establish the circumstances surrounding her comments about her experience in relation to her interactions with our team."

Racecourse Ladies' Days are social highlight events that draw large crowds and a mix of dress and costume traditions. Bell's account highlights how attendees' conduct and exchanges at public sporting and social events can become the subject of public debate when they touch on disability, neurodiversity and personal vulnerability. Bell said she had planned the dress and celebration with family expectations in mind and that wearing the gown had been a way to reclaim a moment she feared she had lost.

The venue did not provide further detail about any steps it would take beyond direct contact with Bell. Bell said she hoped the positive responses since her social media post would "outshine" the abuse she described and that she had been heartened by messages of support.
