For the white and gold part of the corset I find that most of the white and gold poses in Picolitrossos Urn matches. In some, though, the shading is not the same colour. I like the luxurious wrap pose with the bian stockings myself.
Also for the corset: The White Tricorn Hat, Enchanted Book slippers layered with the pink nurse shoes, House Bunny outfit, Pink Sparkle Empire Dress, White Flow Prom Dress, Egyptian White Linen Dress/Wrap, Soft Pink Underwear, Victorian Tea Rose Bustle Skirt, Pink Ribbon Skirt, aaand the Thick Pink Winter Socks can work but it would be a stretch. I've tested all the dresses and they do layer. I'd offer up some screen shots but that's a lot of items! If you find tektek doesn't layer properly with these, though, I'd be more than happy to show you some screen shots.
I don't know about the hair so much, but the Ballerina circlet pretty much blends right into it x3
Biancamella is one of my all time favourites, if you can't tell! I hope this helped
