You can buy T-shirts from sites like ebay, bigshoebazzar, tradus.in, inkfruit.com, myntra.com, 24hoursloot.com, infibeam.com,etc. Have bought Tee's online, no problem as you know the size and how it will fir you. Same does not apply when you consider trousers and jeans.
Where can I get 3/4th's and shorts online? (Not able to find good and cheap ones locally. price range upto 600Rs.)
