Oepns up, strip down the front

New Delhi, Feb 8 (IANS) Bollywood megastar Amitabh Bachchan believes in 'When in Rome, do as the Romans do' and he followed suit while in Kerala recently by donning the local dress code - a crisp white shirt and 'air-conditioned' dhoti, as he puts it.
'Keeping in tune with the phrase 'do in Rome as the Romans do', I order some extraordinary crafted dhoti and sari to be worn... The sari, of course, for the ladies in the house,' Amitabh posted on his blog Sunday night from Cochin.
'So, I wear the dhoti or mundu as it is more colloquially known for the evening and I think there is an appreciation of it,' he added.
The 67-year-old was also ecstatic by the whole procedure while tying the wrap-around.
'The 'dhoti' in all its pristine glamour, tied up around the waist by sheer will power and some dextrous use of the stomach muscle, else it slips down and opens up! It is just a piece of cloth, no buttons, no belts, no clips, nothing.
'Simple, elegant, convenient and with its own characteristic charm and above all - air conditioned at all times. The fall of the main design as a strip down the front to be positioned on the right hip and just around the right knee. Rules of culture,' he added.

Could you please explain to me the emboldened parts?
