How do I ad fullness to my wedding dress...

Have you looked into a crinoline its like a slip with tulle and it suppose to make the dress fuller. P.S. I see no pic.

This dress I attached is not my own, it just protrays the fullness I want.

Crinolin.

You can find crinoline's on the internet for pretty cheap. I bought 5 different slips because I wasn't sure how full I wanted my dress- and then I returned the other 3 (1 was from ebay). Your bridal salon should be able to give you samples to try as well. Warning- stay way from hoops... I used to work in bridal and they are such a pain to deal with.

You would have to add a crinoline or a petticoat, the only concern I would have is since you already had alterations done adding that now might make the dress too short.
