There are a number of characteristics that appeal to me. The sweet collar is the best feature,
I like the curved hem at center front.
And the wide straight sleeves are narrowed with a loop and button.
The fabric is a light weight Japanese cotton - almost voile but opaque. I love the print. I bought mine from Marcy Tilton, but I think that Louise Cutting and Linda Lee have it too. It is a very soft fabric and should be comfortable to wear even during July in the southeastern US.
The buttons are polymer clay, I think. A little short of fabric, I used another light weight cotton print for facings.
This style may be a little dated. It had slightly dropped shoulders that I adjusted so that the sleeve seam falls pretty close to my natural shoulder line. And it is a little long, maybe. Perhaps I should shorten it?
I hope to adapt the details I like to another shirt, perhaps one that is more current looking. But I'll still enjoy wearing this 2015 version. It's the perfect fabric for 97F.
