I spent roughly an hour last night looking at the Colette Patterns Flickr page for Sencha inspiration. By and large, I was not thrilled with a number of the products, but I think I figured it out. People were using very busy fabric, which obscures the pretty design features of the pattern, namely the tucks. Here is a picture from the Colette website (via polkadotoverload)
Unfortunately, that means I'll have to actually acquire some monochromatic fabric--this will be much more difficult (and slow!) than any of us imagined.
Here's another thought, you all can weigh in if you like...what about this top in a translucent gauze? As in, wear-a-camisole-under-it translucent? I might give that a shot in the future.
