I love silks from FallnAngel Creations. Aside from how beautifully baroque they almost inevitably are, they're so easy to fit as they're mostly on clothing layers. So, yay!
These are the Roxi silks, and if you haunt the FallnAngels silks lucky chair, you might be lucky enough to win the set in black.
The only word for these silks is 'stunning'!
As with most FallnAngel silks, they're perfect for all sorts of fantasy roleplay - slave girl, fairy, elf, priestess... I'm sure you'll find a good use for them.
lucky chair (and my favourite of the three).
If you'd like to get them in another colour (purple pictured above - and I'm tempted by the red...) or simply don't have the time to hang around waiting for your letter to come up, you can find the vendors here in the in-world store. Price 365 of your Linden dollars.
(FallnAngel Creations can often be a little cheaper in-world than on marketplace.)
Also, you'll get a giftie rezzed every day you visit the sim (you'll have to hunt for it though), and the random prize giver dishes up a present every 15 mins for someon. One of the prizes is a set of blue silks.
