Cosplay in Appetiser's Creative Hangout

Sooo uh- I kinda need help deciding who I should cosplay for an upcoming con that I'm going to, should I go as Kagamine Len or Miku?

Here are some clothing things I like ^^ I found them on pinterest [check article] and figured I share some. I love a lot of different clothing types but open shoulders, hearts, strings, and not to forgot Purple! are definitely top on the list for me
