Model and corset fan, SyntheticCookie wearing tightly-laced Italian velvet corset, over a firm-control, fifties/sixties-style brief girdle, to prevent the corset from making her lower tummy bulge.
She was actually checking her silhouette in a full length mirror, placed a few metres to the left of the camera. Her hair was blown gently by a 40 cm diameter fan, on its lowest setting.
The image was tweaked slightly in GIMP (an excellent, free, open source alternative to Photoshop) to give it a dreamy, slightly pre raphaelite look.
( GIMP is distributed free with many Linux distros and is also available for MS Windows from gimp.org )
Slightly Pre-Raphaelite
