I picked up some of the Smira II silks from Sa-eela last week.
This full-skirted style is very kirtle-ish so could be worn by lots of girls.
There's also a really wide range of colours, with 11 currently available... so long as you can decide which colour to go for ;) (There are also a couple of chubby packs available if you just can't make up your mind...)
Sa-eela marketplace store (also available in-world, if SL is letting you teleport!)
Skin - Chloe from Bellezza (group gift)
Shape - Naya from Heartsick
Hair- Autumn fae from Inga Wind (free on marketplace)
