This books is rather thin - only 96 pages - but there is not page crammed with gorgeous illustrations or colour pics ( generally two or three large ones on every page!!) that show military costumes in Medieval times. He covers all periods of the Middle Ages, and all levels from Lord and Knights, to bowman and common footsoldier, even women on the campaigns. For those who love history, but have no hands on experience and want to really visualise what each piece of equipment was, how it fit, was worn with other pieces of clothing and accoutrements you cannot find a better resource.
For writers here what you need, you can SEE what you are writing about more clearly with this in conjunction with other history references.
For reenactors, you cannot do without a copy.
Highly recommended for anyone interested in Medieval gear.
