I really love the idea of wearing a Bridal Jacket when you have a sleeveless bridal dress.  It gives you another look for photographs, helps keep you warm in cooler weather  and can also be worn during religious services, where you want a more conservative look.

These can really look nice.

In choosing your wedding jacket, you want to take into account the neckline, the sleeves, and the fabric of your wedding gown.

I found these at p.s. Bridal and I think they are so beautiful.

Etsy.com also has some beautiful bridal jackets, such as these two:

White cashmere cotton bridal shrug - Long sleeves
The wonderful thing about this is that you will be able to wear this so many places after your wedding.  It doesn't JUST look like a bridal jacket.

While this goes from an XS - XL, the designer has this postscript on her page:
"If you want to buy any scarf,cowl,capelet, neckwarmer that can be designed  according to your personel taste, please e-mail me. I prepare your item  in 2 weeks. "

This one is my absolute favorite and  comes in plus sizes.

The designer is also willing to do one for each woman in your bridal party at a reduced bulk discount.
