I love Mary Poppins. It's such a brilliant film, and I hope to read the book (s?) someday! I also really want to see Saving Mr Banks, the film based on the story of how the Mary Poppins film came to be.
The chalk painting section of the film is so iconic, especially the songs and the costumes! I fell in love with Mary's dress after rewatching the film a couple of years ago (I broke the VHS watching it so often and didn't replace it until I was at uni) and slowly worked on my cosplay since then, doing more bits as my skills developed.
I'm so happy with the result! I still need to add a bit of lace onto the chest ruffle (I noticed this detail a few days before the con) but other than that, it's done! Such a fun and long project, and a brilliant learning curve.
