Hi Tippi, I think I missed your introduction, so I'm replying "blind" not knowing anything about you. First, congratulations on getting married!!
I personally love the whole idea of wearing a non-wedding dress to get married in. Who needs a traditional gown?
I don't think you need to go demure - especially if demure is not your style!! I do think it's important to look for something classic and timeless and not too trendy, but most importantly, choose a dress that is 100% your style and YOU.
Is this a style you would normally gravitate towards? Is it "You"?
The birds say to me: someone who is playful and probably artistic, with a gentle soul. Probably a nature-lover. While the cut of the dress says someone who is youthful, loves fashion and has a bent for mod. It's a very intriguing dress!
I have been married twice... the first time I went the traditional route, and I was a complete slave to fashion. The marriage failed but even if it hadn't, I would *still* cringe looking back at the photos!!! AWFUL. The dress, while "traditional," definetly looks dated... stuck in 1990. I regret not wearing something more timeless.
The second marriage, in 2005, was simple and small and I actually chose *not one but three* potential outfits - all off the rack and non-traditional. I allowed my daughters to make the ultimate choice. They chose a romantic drop-waist champagne satin dress with cowl neckline and assymetrical hemline.
I do like the dress much better than the first, and it is pretty. However, I wish I had stuck with my instincts and gone with the classic, simple champagne sheath (hits at the knee), with rhinestone-studded neckline, that I bought from BR. But the girls (preteens then) thought it wasn't "bridal" or romantic enough. However, that sheath dress is totally ME - the other dress, not so much. I can't tell you why one is me and the other isn't; it's just a gut thing.
So I hope all my rambling gives you some guidance: the dress is neither weird nor odd. Trust your instincts. If it is screaming "This is soooo ME," then go for it and don't second-guess yourself.
