Recommended Clothing
Dress is informal and relaxed on most occasions. Smart casual clothes are acceptable at most restaurants and nightspots. Men are generally not expected to wear suits and ties, except in a few of the top formal bars and restaurants in major cities.
In summer a light jacket or sweater should be included in your luggage should the weather turn cooler or you visit the high country. You can expect some rain, so include a light waterproof jacket or coat. Pack warm winter clothing if visiting between May and September and layer your clothing.
