Here is a look at #54 and the bun or hive if placed on top of her head correctly.
Melody will have shoulder length hair so these are some additional styles for her to sport with her 1960s glam.
Notice the uses of the double bows. Walmart has an excellent selection of ribbon and yarn for these styles. My two dolls Marnie and Jacee came with these adorable pink headbands. These are ribbon, therefore they will not be hard to replicate.
Since Melody will have a couple of hats in her collection, I could not resist adding this flowery hat. I saw this musical where two women had hats with flowery print on them.
