Chatuchak Weekend Market (JJ)

If you want maximum variety in one stop, head to Chatuchak. The weekend market spreads across dozens of clothing sections, where you will find every kind of Songkran shirt, from neon florals to cheeky novelty prints. Prices are higher than pure-wholesale districts, but still friendly, especially if you buy two or three pieces from the same stall. Many vendors offer try-ons, and you can pair shirts with waterproof phone pouches and water guns in nearby lanes. Go early to beat the sun, carry cash, and expect to haggle politely. The weekday “JJ Plaza” area also has fashion stalls, but the full experience is Saturday and Sunday.
