Clothing market with fixed prices for bargain hunters and bulk buyers
Word to the wise: Unlike other markets in Beijing, the price is quite a good quality indicator here. But even though the prices are fixed, you can try to haggle.

The city's largest and only clothing market with fixed prices opens at 6am. This place is enormous and you may have to search high and wide before you find something you want, but if you do, you'll be sure to get yourself a bargain.
It's a no "pirate market" but contains mainly Asian brands and the city's biggest assortment of jeans. Given the fixed prices, the ambience is rather relaxed - no one drags you into a shop and there is no squabbling to be had regarding prices. Come as early as possible or be prepared to elbow your way through endless corridors of clothes.
