As for storing the dress, can the boutique you bought it from store it for you? If not and you already have the dress in the closet an idea I had was to either put a fabric softener inside the bag to help keep the gown smelling fresh or to spritz a white hand towel with your fav perfume and put that in the bottom of the bag instead. Then you can air out the dress every now and then before the wedding and replace the fabric softener or respritz the towel. Hope that helps!
ok i''m not normally a tiara gal, but looking at your pictures, i think you rock it! it goes great with your veil and with the style of your dress. i think it all looks really nice together!
