Very true Joerg! I think the beauty of the pinup project is that the painter's imagination can run wild. The painter is not locked into any specific palette. Five the of the six Elvgren poses (or similar) I posted below would be suitable. Remove the clothing and strip the piece down to basic lingerie - knickers, suspender belt, bra, stockings, and shoes. The stockings only need to have a raised ridge at the top (no raised seam down the back of the leg; that never looks right). Make the lingerie (and the hair style) period correct if necessary; do the research into design and construction. Make sure the anatomy, proportions, and perspective are right - especially the face. The face will be the window to the soul of the piece. Keep the piece at 54mm at the smallest; it will allow everyone to take advantage of the details and the detail painting, but don't go larger than 80mm to keep the costs down. Let the painter decide on how to depict the material - opaque, sheer, rubber, shiny vinyl, leather, silk, satin, etc.; as well as colors, patterns, and/or any decorative embroidery.
I've also been thinking (dangerous) about my 12-piece calender pinup set idea in 30mm - 54mm. If not 12, then how about four pieces on a seasonal theme - winter, spring, summer, and fall? They don't have to be keyed to holidays (think Xmas), but can be centered around the climate, much like Alphonse Mucha did his art nouveau four seasons set.
Sunny now, taking MGs out!
Cheers,
Glen
