The above article, posted on inweddingdress.com today, discusses different kinds of wedding dresses and how they are each appropriate for different settings.
Semi-formal wedding gowns are very popular for outdoor weddings - mountain settings, beaches, and anywhere where you wouldn't want your long train getting grass-stained.
Ann Taylor has quite a few short wedding dresses that could look great in any of these settings, along with indoor ones, too.
This "Confetti Dress" (left) from Ann Taylor is described as "chic" and "vintage," and I couldn't agree more. It's modern and sleek, perfect for an outdoor spring wedding.
Then, they have this GREAT strapless dress, for spring or summer. I can picture a bride walking through a field of flowers or something of the like wearing this. (Below)
