French Porcelain Princess! I wouldn't wear a train to a wedding unless I was the bride. I do think those dresses with trains would make lovely bridal gowns!!!
Well, these really aren't a style I would wear, but #2 is my favorite of the 4. The pink and purple dresses seem too little-girly, but that brooding blue and water-color pattern give a much more adult vibe. And the train adds a lot to the dress, too.
Investment piece? Yeah if you have opportunity to wear it. I live a more realistic life where I don't need a floor length pink sequined dress in my closet.
Princess Luna. Some of the others are giving Bridesmaid vibes. But asking for permission from the bride or MOH is always an option. Especially if it's a small wedding
