The 22-year-old student designer has received €10,000 and her winning design, 'Music in the Glen', will be manufactured and sold in selected Dunnes Stores nationwide, priced at €55.
This year, the theme for the awards was Irish heritage, roots, ties and family.
Sinéad said of her design: “My inspiration for my garment for this competition took its roots in traditional Irish music. Both my sisters and I play the fiddle. Both of my Grandmothers were avid knitters, and my Grandmother on my father's side recently kitted out myself and my sisters, and nearly all of our cousins with expertly - made Aran Jumpers! The music and language have definitely been passed down through the generations”.
Renowned Irish fashion designer Peter O'Brien judged the awards alongside Carolyn Donnelly from Dunnes Stores. He said of the awrads: “It is exciting to see emerging new talent; it gives one hope, particularly in the last few recessionary years. It’s heartening to see that despite cutbacks, doom and gloom, the exuberance and talent of our young designers is supported in this incredible way by Persil.”
