This is one of those dresses you will live in all summer long,” according to vegan chef and co-creator Holly White. The Holly Dress is €325 and is available from this Saturday at www.niamhoneill.com and Arnotts.

From a selection at Om Diva boutique and www.byjenbyrne.com 

We spotted Jen Byrne’s beautiful blouses and accessory collars in Om Diva’s Atelier 27 last week. With a strong focus on sustainability, each piece is reimagined from vintage textiles – think lace tablecloths transformed into skirts, vintage Laura Ashley fabrics re-created as shirts, old punt coins that become charming necklaces. The pretty printed blouses are perfect for summer – and the sweet collars (with prices from €40) would make a gorgeous keepsake gift for someone special, all while supporting a small local business and sustainable Irish design. www.byjenbyrne.com
