For a change of scenery from Bangkok’s ubiquitous malls, head to O.P. Garden (Soi 36, Charoenkrung Rd.), a collection of boutiques in colonial-style houses. Serindia Gallery (Units 3101 and 3201; 66-2/238-6410) is a tranquil space with Himalayan-inspired art and photography by Asian and expat artists. Across the way, designer Atinuj Atty Tantivit sells inventive international jewelry in her Atta Gallery (Unit 1109; 66-2/238-6422). In the Siam shopping district, the team behind local cult label It’s Happened to Be a Closet recently launched Palette (979 Rama I Rd.; 66/81-754-1791), an affordable line of breezy tops and dresses in vivid colors. The winding sois off Sukhumvit Road contain some of the city’s most eclectic boutiques. Enlever Ses Vêtements (59/3 Soi 23, Sukhumvit Rd.; 66-2/260-4660) puts a fashion-forward spin on the city’s bespoke clothing tradition with suits in linen and high-tech Japanese fabrics. Irresistible (45 MSI Tower II, Soi 31, Sukhumvit Rd.; 66-2/662-1050) stocks cicada-shaped silver boxes and clutches made of shell and inky labradorite, while Asana (235/32 Soi 31, Sukhumvit Rd.; 66-2/662-3118) displays contemporary wood furniture by Thai designers. The shop has international shipping, though pieces such as mango-wood vases can easily fit into a carry-on.
