I think they''ve fallen a little bit out of favor these days, but if you want to wear one, that''s your choice! I personally think they''re pretty, but I didn''t wear one. David''s Bridal has a few options for headpieces, so you could start your search there.
I bought mine at my bridal shop. Here's a quick pic..I put it on after I got my bridal portraits done and played in it since I had my hair done.
ETA: Sorry it's not a good photo, took it w/ my cell. I plan on wearing it at the reception when I take my veil off. It was just waaaay too much w/ the veil.
I couldn''t find the site I was looking for but I did find this: http://www.crowndesigners.com/. They seem to have some nice looking stuff. I particularly like the one on their home page. They say they do custom work too.
Im wearing one too! not many birdes wear them lately but i always wanted to as well.
So i say go for it. Mine was my MOH''s so its my something borrowed.
