In esoteric lore, sylphs were spirits of the air, so the diaphanous fabrics and decorative feather are perfectly suited. It's a great outfit for bellydancers, kajirae, fae, elementals, maybe even for kokarri of Mystara!
Important: the outfit includes a rigged mesh corset (plus alpha) in one size only. So be sure to try the demo and make sure you're happy with the fit or any tweaks you might need to make to your shape.
If you look closely, you can also catch a glimpse of the bonus alternate clothing layer top in this shot.
Anyway, there's lots of stuff in the box. Mesh components include the corset, corset jewels, sleeves (with or without armbands), and arm jewels. Then there's an alpha for the corset, two clothing layer tops, a modesty thong, prim armbands, bracelets and legbands.
It comes in four highly covetable colours (if there'd been a fatpack, I'd so have bought it), but Passion (red) was my preference at the moment of purchase. It's also available with gold, black or white silks (the corset remains the same).
Sylph costs 595L and you can find it on the marketplace or follow the slurl to the in-world Caverna Obscura store. But don't forget that demo!
