Your old man's favourite holiday shirt is now your best summer asset.

When I think of Hawaiian shirts I picture my Dad in a horribly bright button up he purchased specifically for a P&O cruise around the South Pacific. While I thought it was a fashion faux pa, it turns out my old man might be more in touch with the latest trends than I thought.

The often derided item of clothing is currently firing among celebrities and regular blokes alike. Jared Leto, Harry Styles and Justin Bieber have all been spotted flaunting colourful designs - the more outrageous the better, apparently. The popularity of the Hawaiian shirt has even seen luxury fashion brands such as Gucci and Prada getting in on the act, releasing their own variations of the party shirt at equally insane prices.

With almost every clothing outlet now stocking Hawaiian shirts it can be difficult to know what's hot and what's not, so here's our guide to the best Hawaiian shirts for the summer.

Prada Camp-Collar Printed Voile Shirt

Prada Hawaiian Shirt

If you're a fan of Tom Selleck than this one's for you. Looking remarkably similar to a shirt the moustached Selleck wore on hit 80's series Magnum P.I., this red Prada shirt displays Hawaiian hibiscus flowers and a picturesque palm-lined beach on the back.

Gucci Hawaiian Print Shirt

Gucci Hawaiian Shirt

Bold, vibrant and with one hell of a price tag, Gucci have gone all out with their take on the Hawaiian shirt. The 100% silk shirt features a black panther, African sunrise and a variety of tropical flowers. For those who like to stand out in a crowd. To be honest, though, you'd be able to buy the exact same print on a shirt in a Waikiki market for $10.
