The pattern comes from the blog, Straightgrain.
It's the first time I've ever attempted to line an article of clothing. And I used a great tutorial specifically on lining dresses from Kitschycoo.
If you make this dress, my only advice would be to sew less on the back seam as my niece had trouble getting her head into it, so I ended up ripping the seam and resewing in order to accommodate her head. Also, the tutorial recommends using elastic and a button to close up the back. I went for a clasp closure instead as I thought it would be easier to sew.
