You guys have me pegged on the pattern. Generally, I like plaid, but it comes down to that psychological comfort thing. I definitely gravitate towards solids, so this would be stretching my boundaries a little.
If I got the dress, I'd use eShakti's custom-sizing. The good thing about that is that, based on my other dresses from them, I know it would fit perfectly. The bad thing is, if I decided I didn't like it, I'd probably either lose a little (the customization fee, at least) on the return or have to accept store credit, which wouldn't be terrible, but also wouldn't be ideal.
