What’s the Occasion? What to wear on your next big day out

From race days to weddings, most of us will have at least one reason to dress up this summer, and the definition of 'occasionwear' has never been more varied! From beach weddings to garden parties, striking the right sartorial note can feel daunting when anything goes, but whatever the occasion, you can dial up the style with our ultimate Guest Edit of the season's most fool-proof looks.

Carolyn Moore reports.

Best dressed guest. Designed by a woman, for women, Fiona Heaney's Fee G brand has become the Irish woman's wedding season go-to. Our pick – fit for any summer occasion – is this deluxe jacquard prom-style dress, €337, Noirin’s Boutique, Millstreet.

In full bloom. For laid back summer style befitting a beach wedding or a garden party, you can’t beat the easy appeal of floaty florals. Scarf print cut out halter dress, €131.34, ASOS.com.

Block party. Colour always makes statement, and none more so than yellow. Still remember Amal Clooney’s dress at last year’s royal wedding? Thought so. Open back jumpsuit, €77, Warehouse.

Tea for you. A vintage-style tea dress is the perfect choice for a chic country wedding. Top it off with a neat little pillbox for extra style points. Button-down Ferrier tea dress, €275, hobbs.co.uk.

That’s a wrap. As more couples embrace casual weddings, it can be hard to get a read on the dress code, but you can’t go wrong with a wrap dress. Veronica dress by Phase Eight, €185, Debenhams.

Cut a dash. The Caroline Kilkenny brand is known for flattering cuts and standout prints. With longer length cap sleeves and rouching, their abstract print Ellis shift is a case-in-point. €297, Arnotts.

Suits you. Dressing up doesn’t have to involve a dress. Increasingly popular on the red carpet, trouser suits make for standout wedding style. Anthea linen jacket, €225, and trousers, €135, hobbs.co.uk.

Flower power. Free spirits can channel their inner boho queens while hitting the right note for formal occasions. Filomena embroidered tulle maxi dress by Frock and Frill, €200, littlewoodsireland.ie.

Frill seeker. Summer-ready style, glistening with a subtle metallic finish and just waiting for tanned limbs and on-trend wicker accessories. Teracotta Fianna asymmetric dress, €124, Monsoon.

Pretty in pink. Say I do to classic prom-styles and fit-and-flare shapes. Simple enough to take bold accessories, strong enough to fly solo, they're fit for any occasion. Lola dress by Olivia Rubin, €515, Brown Thomas.
