Reply To: Men Shteiging on Shavuos, Wearing Pants

It may be considered a lack of kavod hatorah to learn shavuos, or any night, sans pants. I think one is not permitted to enter a shul sans pants, even if he does not plan on learning. Also, since many shuls turn the AC up high to help facilitate staying awake, pants would be a good idea so as not to freeze. Of course, a good stadium blanket would do the trick too.
