Nightingale Olympic 
Pahurat intersection, 02-221-9733. Open Mon-Sat 9am-5:30pm.
Your great grandparents will tell you that this haunted-looking seven-story building was once a very popular department store standing proud even before the first big Central. Well, Thailand’s first mall is still alive and creepy. Rather than closing up shop, the owners just decided to keep selling the old stock, even though they have had to downsize to just two stories. You’ll be journeying back in time through a pile of old golf clubs, underwear, musical instruments, expired perfumes and men’s shoes. It’s really, never-before-used vintage—what could be better? A customer once bought authentic Fred Perry shorts there for under B1,000, and Fred Perry doesn’t even make those shorts anymore.
Talad Naew Naew, Wang Lang Market
Siriraj Hospital, 2 Prannok road, Siriraj, Bangkok Noi.
How to get there: Take the BTS to Saphan Taksin and hop on the Chao Praya Express boat to the “Wang Lang/Siriraj” pier. Talad Naew Naew is located in the middle of Wang Lang. It is open everyday but the best time to go is around lunch hour, when all the vendors are open.
In the shadow of Siriraj Hospital and surrounded by street food, Wang Lang is packed with secondhand clothes, bags and shoes. The secondhand section of the market is located in the middle and is divided into four zones. Most of the shops here have no official names, but they usually stick to their spot so you could come back and find them again if you had to. Mondays and Wednesdays are their clearance days to make room for new stuff. The first zone is the Ton Poh block (Open daily from 8:30am-7pm. B200-500) and it sells bags and high heels, fashion boots and flats. The Pra Too Kiew block (Open daily from 9am-6pm. B350-550) also does shoes and bags as well as some clothes and accessories, though not quite as nice as the stuff in Ton Poh, so you have to be willing to dig around for something good. The most popular shop here is the secondhand Converse shop. The third and fourth zones are called Talad Neaw Neaw, or the indie market (Open daily from 1pm-6pm, B100-550). You can also find handbags, jeans and other clothes there, but the overall vibe is way more hip than the other two sections.
Talad Rod Fai (ตลาดนัดรถไฟ)
Sri Nagarindra soi 51, Khwaeng Nong Bon, Khet Prawet, Krungthep Mahanakorn 10250 (GPS: 13.691867,100.650171) https://www.facebook.com/taradrodfi
Talad Rod Fai or Train Market was the hottest night spot for secondhand shoppers until they moved away from their original location on Kampaengpetch Rd. Now in a brand new location behind Seacon Square on Srinakarin road, the market has become more spacious than before. I am very happy that Talad Rot Fai has found a new home and it remains a smorgasbord of oddball merchandise. The new market is split up into 3 zones; the weekend market (original talad rod fai) – open Friday – Sunday from 5pm to midnight; the Plaza which houses a variety of shops – open Tuesday – Sunday; and a restaurant section.
Apart from the clothing, bags and shoes, there are some more unusual items from people’s personal collections to be discovered. You can find bikes (B4,000-6,000), Nintendo game consoles (B4,500) and even a 30-year-old Russian camera (B2,000)—all of them in working condition. You can even buy bike parts and assemble your own bike. The retro home décor includes leather sofas, chandeliers and old school telephones.
Not as easy to get there as before, but worth the trek. Take the BTS to Punnawithi station and then catch a motocycle taxi to Talad Rot Fai. Or take the Airport Rail Link Line to Hua Mak station and catch a taxi from there to Talad Rot Fai. Its just behind Seacon Square.
Chatuchak Weekend Market
Kampaengpetch Rd., MRT Kapaengpetch, MRT Suan Chatuchak and BTS Suan Chatuchak. Open sat-Sun 11am-7pm.
One of the oldest destinations for indie shoppers, Chatuchak continues to evolve to serve the needs of its youthful customer base, awash in street fashion items, handmade stuff and a host of secondhand items. The market is divided into 21 sections, but the vintage finds are concentrated in sections 5 and 6. Clothing is priced between B200-550, though some rare leather jackets could cost up to B2,000, and secondhand jeans start at B1,000. T-shirts are often sold in bulk for B20 a piece, or B800 for rare rock band t-shirts. There’s also lots of old vinyl here, starting at B500 for the original soundtrack of Grease (1978) while collector’s specials like Woodstock 1969 go for B2,500.
Ratchada Night Bazaar
MRT Ladprao. Open Saturday Nights. Starting from 6pm but most vendors don’t come till 8pm or later and stay till well after midnight.
This dirt-filled wasteland used to be between the city’s Ratchada and Ladprao MRT stations, but has now moved down the road to the other side of the Ladprao MRT station due to construction. It was once just a tiny Bangkok market used as a trading hub for vintage car owners in search of spare parts to revive their old engines. Somewhere along the way the trading of prized Vespas, VW vans and 1950s corvettes got overshadowed by tin toys, vintage cameras, vinyls, gramophones, framed newspaper clippings of Thai political uprisings, first editions famous Thai books and second-hand clothes and shoes. Fashionistas especially love Ratchada, which has everything from mod dresses and thick-framed glasses to boots and baby-doll pumps. The old cars and motorbikes are still there too, making it a bizarrely great place for couples to explore together.
