1. Sandals and socks

2. Sun cloaks

Sunsibility make UV ray protective clothing for the paranoid. This one is factor 50, but we’d probably suggest just staying indoors – for everyone’s sake.

3. Crocs

Listen lads, we know they're comfortable and yes, the ventilation is next to none. These rubbery clogs always come with a rail of excuses, but unless you're under 8 and by a pool, there are no free passes. See also: jelly shoes.

4. Too much pastel

You're on the Aran Islands, not a beach club in the Hamptons.

5. Shark tooth necklace

Unless you wrestled the shark to get it, there's no reason it should be hanging around your neck.

6. Hawaiian Shirt

Penneys has a sale on them, they'll do for a change the holidays. No.

7. Mirrored sunglasses

Simply criminal. You should only ever see these when your face is reflected in them having just been arrested by the cops on your J1.

8. Visor cap

Should never been seen anywhere outside of the tennis court, or 1996.

9. Short shorts

Deduct a further 10 points if they're denim.

10. Mesh in any shape or form

Sure, it's 'grand and cool on you', but think of those around you. Solid blocks of cotton are poorly underrated.
