I have always been very impressed by the ability of Thai ladies to cover themselves up so that there knickers are never flashed even when wearing the tiniest of skirts.
A bag on the lap whilst riding side saddle will suffice. A book or folder behind them whilst climbing stairs.
Living next to a University means that lots of lovely young ladies ride past side saddle everyday but not one of them ever slips up.
On the odd rare occasion that you get a good flash of the gusset I am always very happy and feel the urge to shout for joy.
Have you noticed these skills as well?
