SHE comes from fashion royalty and is fast making a name for herself with a luxury range of shoes and handbags.
"The style I envisage for the way Irish people dress is very elegant and very sophisticated," Lucy told the Herald.
"It is very different to the London look and is more elegant and charming."
Irish fashionistas are often criticised for having a more conservative take on style than their counterparts in fashion capitals like London and New York, but Lucy disagrees.
Well-known names, such as TV presenter Karen Koster and top model Roz Purcell, often hit the right balance between creativity and sophistication. And this is our best fashion trait, according to Lucy.
"I think Irish style is more timeless in that women are clever and pick pieces that they can wear over and over again," she said.
"In London you would see people with one-off pieces that are looking for attention, but you might wear it only once."
The 39-year-old said her own label, which provides luxury shoes at an average price of ¿200, is in great shape.
Her range is currently stocked in upmarket store Harvey Nichols, but Lucy said it could be some time before she stocks another collection in Dublin.
"If Harvey Nichols does well then we'll see, but the collection has to be in a store that has the same level of exclusivity, somewhere like Brown Thomas," Lucy said.
The fashion designer is looking forward to her return to Dublin this weekend.
Lucy touches down on Saturday and will stay the night before attending the Hennessy Gold Cup at Leopardstown Racecourse this Sunday.
She will be there to judge the Hennessey Best Accessories competition, in association with Harvey Nichols.
