First up - the Lucie muslin.
I made the largest size, but without any seam allowances added in. It is a bit on the large side, but still wearable. I think it will be great when it is really hot out. I plan to make another wearable muslin from stash fabric a couple sizes down, though - to perfect the fit. I like the length as given. I added some width to the skirt by just doing two 54" wide pieces, selvage to selvage for cheater finished side seams.
I was kind of worried about the slender French sizing and my decidedly pear-shaped American body... but I think I am getting it sorted for next time around and amazingly, though the bodice is oversized, it doesn't actually fall off my shoulders. It almost does, but no amount of wiggling and squirming around actually makes if fall off the shoulder - so that is a good thing, indeed.
My fabric is thrifted - 80s or 90s rayon, I think. or a really soft cotton/poly blend. I bought it in 2014 when I was rebuilding a stash. It's light and floaty royal blue with black squares.
I did my own thing for the finishing. I lined the bodice and left the skirt a single layer. I sewed both the bodice and the lining separately at the side and shoulder seams, then slipped one turned right side out into one turned inside out.
