- Hmm, practical - not how one would describe Baroness getups, since the goal in these books is maximum sex and violence. Here's one from #5, "Operation Doomsday", a skintight thermal suit that she's using in the Arctic:
"Inga handed her the hotsuit. It looked as flimsy as a body stocking: a smooth silky thing that you could have squeezed into a fist. But it wedded NASA's space age technology to the Air Force's survival research. There was an inner layer that somehow managed to be fluffy, despite the fact that it was thinner than a silk kerchief. The trick was a superdense mat of synthetic pressed fiber with thousands of microscopic air pockets and projecting cilia per square inch. There was a metallic middle layer that reflected back body heat. And another layer that trapped heat. And a tough, smooth, waterproof outer layer with an oddly structured cross section that had been developed, at a cost of millions, for a new type of skin-tight space suit. The polymer material acted as an impermeable membrane for anything - gases or liquid - trying to get in. But it let the wearer's body breathe, passing through moisture, carbon dioxide and - through pinpoint valves that became flaccid past a certain temperature - excessive body heat.
"Penelope shucked off the long johns and stood naked in the firelight. The flames played ruddy highlights on her smooth long limbs and rippling musculature. Her body was as taut and functional as any hunting animal's. She reached for the synthetic pelt that modern technology had made for her.
"It was all one piece. She pushed her feet into the boots, soft and flexible as suede slippers, and pulled the hotsuit up her legs. It fit like a second skin, showing the powerful calf muscles and long line of the thigh. The upper part had built-in support; nothing, not even a bra, could be allowed to interfere with the efficient thermal design. The top held her breasts firmly but comfortably, allowing them to move without hindering her capacity for violent action. There were thin, sensitive gloves of the same space age materials, with extra heating wires for the fingers, and an attached hood and face mask, with the flaring, tip-up goggles that looked like cat's eyes.
"The battery, a flat flexible package of plastic electrolytes, fit into a pocket at the thigh. It fed a network of fine platinum wires embedded in the suit.
" 'You look like the Snow Maiden,' Inga said with a trace of awe.
"It was a good description. The white clinging garment gave her the appearance of a naked woman, sculptured in snow, with a spectral featureless face out of northern myth."
This is the B series all over - intricate (and accurate!) technical detail in service of lasciviousness. The materials he's describing sound like the research versions of Polartec and Gortex, neither of which were around in the early 70s. Moffitt did some amazing research for this series, far beyond what even Fleming did.
However, she does not have a standard outfit for her exploits. Every book has some different kind of catsuit. She's not a superhero (although she's extraordinarily strong and tough), and so doesn't use a costume.
