Mermaid and merman role-play in Second Life is perennially popular (sometimes combined with pirate role-play). I have had a mermaid avatar in Second Life for as long as I can remember, although I must confess that I do not pull her out that often nowadays.
Here is what my mermaid avatar looked like before her makeover, a system-layers-and-flexiprims look cobbled together from various freebie mermaid outfits I picked up over the years (the lovely mesh tail was a recent free hunt gift from Solas NaGealai of BlueMoon Enterprise):

Well, I decided to give my mermaid one of my patented fifteen-minute avatar makeovers today, to move from a classic, system avatar to 100% mesh!
Here is what she looks like now:


This avatar is wearing:
Mesh Head: the Freya Bento mesh head from Catwa (free group gift; the Catwa group is free to join; more information here). TODAY IS THE LAST DAY YOU CAN PICK UP THIS FABULOUS FREEBIE!
Lipstick: HD Lipstick (part of the Freya package, this comes in a wide variety of colours).
Hair: this absolutely perfect mermaid hair is called Spring Briar Fae Hair, which I picked up for free at a Crazy Hair Hunt many years ago now. I combined it with a hairbase from the Catwa Master HUD, tinting both it and the eyebrows on the Freya head to match.
Mesh Body: Classic mesh body by Meshbody (L$1 group gift; The Shops! group is free to join; more information here).
Choker: This beautiful golden Nefert choker is a free group gift from Poison Rouge at the current round of the Très Chic shopping event (you can join the Très Chic group for free). It hides the slight mismatch between the skin tones on the Freya head and Classic body perfectly!
Mermaid Bra and Tail: This is a freebie, too! Just join the Arata Shouten group for free, and check the group notices for this lovely gift (which was my impetus for making this blogpost). You’ll need to alpha out your legs, of course, using the included Classic Meshbody HUD.
Mermaid Animation Override: I picked up this mermaid AO as part of a free hunt gift at FallnAngel Creations many years ago. (If you hunt around at the various mermaid role-play areas in SL, you might find a freebie mermaid/merman AO.)
TOTAL COST FOR THIS AVATAR LOOK: ONLY L$1! (for the Classic mesh body from Meshbody). Everything else was free!
