A few weeks ago I made up McCall's 6745, in the halter dress view. I don't usually make halter styles, not because of the open back (although those can be hard to fit), but because usually they are too cleavagey in front. This one didn't look too low on the envelope, though, so I gave it a try.
I am very happy with the results!
Here is a close up of the piping and the print:
Speaking of being in no mood for muslins, I began this pattern last night without one. I lucked out again, because I think the fit is working out. Whew! It's the same Fashion Star line that I just made the black lace shorts out of, so I was pretty confident it would be a similar fit. Maybe I'm naive, haha.
