I purchased two formal shirts and used for 4 years with no change in there color and cloth quality.The Till the time I used it the colour was as its new shirt and no lents. The shirts are good to waer in any season.
I purchased each one of around 2200 but the cost was justified. If you will see the cloth quality It will explain it by own. When I felt bored wearing it for 4 years I gave it to some one needy and he is also liking it. Now If it comes matter of formals. I would always recommend Arrow. The price is a little high but that is worth to the cloth quality.
