In my yeshiva I expect all my bocherim to wear lululemon stretchy pants not only that but they are mandated to also wear the stretchy Zara white shirts, so that when my rich bal habatish donors walk through my front doors of my yeshiva they know that the minimum amount of a donation is 50,000 dollars, that is how my yeshiva is run. If anyone would like to donate please let me know, tiska limitzvos
