Answer:
Malls offer shopping in a nice ac environment with department stores inside them or individual stores selling fashion that comes in sizes and real brands whether they are local Thai brands or international, prices are ok in the malls usually all he time with the Thai brands but international brands can be pricey so best to buy in the sales, markets offer
another style of shopping with plenty of bargains to be had but sizing can began issue and what brands that are on offer are copies, both options are a fun day out but these days I prefer the excellent malls Bangkok has to offer like spam paragon and the others,close by, MBK has lots of copies!!
