Shopping and Street Food: Bangkok is one of the best cities in the world for shopping and sampling tasty snacks from street vendors. While out shopping, most travelers choose to wear casual, lightweight clothing like a t-shirt and shorts , or a thin jumpsuit. Make sure to wear comfortable shoes, and during the monsoon season don’t forget your rain jacket and umbrella.
Dining and Nightlife: If you like to live it up while on vacation, Bangkok is the perfect place to pretend to be the King of Thailand without breaking the bank. Here, you can enjoy upscale restaurants and nightclubs for a fraction of the cost back home. For a night in the city, wear a lightweight skirt or a button-up shirt and slacks, and make sure to wear good walking shoes so you can hit multiple venues in one night.
Touring the Sights: If you plan to tour Bangkok’s temples, parks, and other attractions, you’ll want to dress for the strong tropical sun. Wear shorts or hiking pants and a breathable shirt , and protect yourself from getting burned with a sunhat , glasses , and sunscreen . Make sure to wear comfortable footwear and pack a jacket in your bag in case you get caught in an afternoon squall.
