Sure, you could go for a godawful polyester number from a big ol' bridal store... or you could get the dresses made. Colette Patterns is a one-woman business working to create vintage-inspired dress patterns that you'd actually want to wear. As well as looking good, if you took this route you'd be supporting an independent craftsperson when buying the pattern, then (likely) another small businesswoman who makes your dresses; instead of a faceless corporation exploiting cheap labour. I think the dress above would be beautiful in raw silk. Or the dress below would be lovely for a casual outdoor wedding in lightweight cotton. Either way, unqiue, whimsical and sure as heck something I'd be likely to wear again.
