I made this for Thing 2 to wear to my brother's wedding last weekend. I had been so unmotivated to sew that I ended up sewing this the night before I left, and I did some handstitching to finish it in the last 30 minutes of the drive to the church! Hopefully I won't do something like that again any time soon! However, it did get done, and it fit - well enough for this wedding, anyway. Unfortunately, since Thing 2 is so tall, this size (M - 12 months) is not long enough in the torso, and once his diaper starts to get soggy, the snaps at the crotch start to bulge. But I like the way the finished product looks, so I've already bought more fabric to use for a short-leg version in the next size up. I think it'll be nice and cool for church this summer.
