Her fashion label's famous clients included Jacqueline Kennedy.Said to have put Irish fashion on the map, she was a member of the "Big Three" Irish fashion designers (along with Irene Gilbert and Raymond Kenna/Kay Peterson), and was described by former Taoiseach (prime minister) Jack Lynch as: "a national treasure".
Her activities were covered in both the fashion press and the social columns of publications such as the Hollywood Reporter.
Described by Bettina Ballard as a "personable milk-skinned Irish charmer", she came to the notice of Carmel Snow, the Dalkey-born editor of Harpers Bazaar.
