Re: My experience at a Pakistani beach...
No
In windy circumstances shalwaar portion not lifted because there is azarband.
Why someone wear see thru thin material unintentionally? In rain one should have umbrella there will be no problem.
Normal surrounding by beautiful people is not a problem at all. SK is not tight dress like pant so if some thing happened below no body will notice but in case of pant every body will know.
Wearing underwear under shalwar does not save you from possible embarassment. but not wearing underwear under pant could embarrass you.
