I can't see it when I click on the link but I saw a butterfly dress when I clicked on the collections part... I think it's very pretty and it fits perfectly with you butterfly bridal shower theme.
That is a different party. In Mexico you always have 2 bridal showers, one with you mother's friends (that is the butterfly theme), and the younger crowed bridal shower (which was going to be moroccan theme buuuut i had to change the theme since someone copied my ideas).
