The Corset: a cultural history by Valerie Steele. Paperback book. Very good condition, spine unbroken, some very faint shelf-wear to the cover. 4th ed. Published 2005 (original was 2001).
The text is written perfectly and accompanied by historical coloured illustrations. The pages are larger than A4 and make the reading vastly easier and more enjoyable. Valerie Steele is an expert in the field and knows her craft very well, I'll be looking up more of her works to read as an inspiring fashion historian!
