I got an ivory satin purse with a large rosette from JCrew on sale for about $60. It''s not available from JCrew anymore but I just found several on eBay if you like it.
I had mine custom made on etsy.com for about $20. I wanted something more casual that didn''t look bridal, though, so I could use it again. Here''s what I went with (it goes with our wedding colors):
I actually already have one at home. It''s vintage, and cost me $15. I probably won''t use it, but it''s a cute bag for nights out. I''ll go ahead and post pics of the other two that are heading my way.
