My top 2 choices are lumpy space princess from adventure or the one and only Ariel from the little mermaid.
The little mermaid is my favourite Disney princess and i have always wanted to be a mermaid when i grow up so this just makes sense.
LSP is new to my list of cosplay to try but shes purple and lumpy and im purple and lumpy......i thinkbyou all know where im going with this also the chance to dress fully in tulle is tempting.
While halloween isnt strictly limited to scary atire unfortunately niether of these quite tickle my spooky bone so ive thrown in a more spooky option.
The witch.....the easy low effort go to for every busy mom.
Definitely not exciting but i could make it work and i have never done it before.
