Is It OK For Women to Wear Jeans and a T-shirt to a Wedding? [POLL]

Don't get me wrong...I don't think you need to dress up everywhere you go. I just think the way you dress shows a level of respect. You wouldn't want your banker to be wearing pajama pants and you wouldn't show up to a funeral in jeans and a t-shirt so why in the world would you show up to a wedding with jeans on. Maybe weddings are more casual than they use to be and I am over thinking it. You tell me.
