At the moment, culottes are available practically everywhere -- in roadside stalls and in designer stores. In Mumbai, they are available at Linking Road and Hill Road in Bandra, at Colaba Causeway and at exclusive shops like Promod and Mango. So whether you want to spend Rs 250 or Rs 2500 on a pair is up to you!
Make sure, however, to buy a pair that's well-cut -- if you don't, you may just end up looking like one of the boys in their scruffy three-fourths!
