I wanted to ask, if it's possible for this summer of 2025, could you do, or do you plan, a Mermaid Melody cosplay in her mermaid form and swim underwater? It's to take advantage of the summer and The idea came to me from this cosplay by a Japanese cosplayer. Greetings.

Short answer: Yes, it is possible
Long answer: Yes, but I habe no fucking idea how

Lock up underwater photoshootings and such
It needs special equipment

And about the mermaid-tail, look that up too

Tail? Trivial
Underwater equipment? very GoPro comes with underwater case
Knowledge of how to do that without fucking drowing? now THAT is the difficult part.
First learn how to mermiaid-swim and tran to be able to hold your breath for at LEAST 1 minute, THEN think of doing underwater photoshots. Otherwise it WILL be a disaster.
