Next time I make this dress, which I will, since I love it, I'll add a little extra seam allowance and do French seams. Do you use French seams? You really should. It's when you seam a seam once with the right sides showing, then again on the inside to hide the raw edges. It makes everything look so much neater, and results in less frayed fabric and random strings hanging out of your garments. It takes longer to do, but the end product is worth it.
Hope you're enjoying the summer weather!
