I cut this dress in a size 6 with no alterations to anything at all. However, I can't wear it to Thanksgiving dinner unless I want to either seriously limit my food intake or bust a zipper. But on a normal day? No issues. The straps are attached to the bodice last, which makes fitting the bodice quite easy. I had no issues with gaping or extra space at the chest, but I should point out here that Sewaholic patterns are designed with pear shapes in mind (read: I have a very small chest).
I used a basic cotton lawn with a polyester lining. I am slowly learning my lesson about lining fabric. I used a Bemberg rayon to line my Hazel dress, and even though this poly feels pretty much the same to the touch, it doesn't breath the same way. Not a huge deal in a dress like this, but I think I might spring for the Bemberg from now on. And if you squint at the picture above, you can just barely make out my stitches at the hem. I used a decorative stitch that looks like a vine with leaves to match my fabric. Because I am a nerd. But I don't care because I now have a new favorite dress. I feel like I say that every time I make a new one, but I really mean it this time. ;-)
