My fabric is a rayon and something-or-other mix - very drapey, and obviously very wrinkle-prone. A collar in the same fabric would have been too boring, and I managed to find a scrap of some gauzy almost cheesecloth type stuff in a drawer - but the colour worked. Even so, with interfacing it does its job. I added an extra button, because I didn't want to leave one lonely button with no mates. (That's a good reason, no?) Oh - it definitely needed a snap above the top button, otherwise the poor collar kept drooping and looking rather sad.
This one's just so that you can see the lines of the sleeve (this is actually a "mistake" picture, but it does serve a purpose).
I suppose I do like this blouse. Very comfortable, and very cool to wear. I did end up popping on a belt when I had to go out in public. Looks too pyjama-like as is, at least to my eye. Or may-be I'm just not built for the loose and baggy trend that I'm seeing on the streets. Too long to tuck into pants, but I could definitely tuck it into a skirt, as per View A.
