Not cheap, but should be able to be ordered from libraries: John Styles, The Dress of the People, Yale University Press 2008 looks at everyday clothes and how they were worn in the 18th cent, a time when new fabrics - especially washable cottons from India - were transforming British fashions for the wealthier classes, and 'trickling down' to the poor. In the 19th cent, relatively cheap washable machine-spun and woven linens and (more important) cottons from British factories (and new chemical dyes) brought another great change to British dress. Cleanliness was valued by this time, too, even if was not always easy to achive - though 19th century city sanitation, the expansion of commercial laundires and the washerwoman profession (there was a famous washerwomen's strike in the USA in 1881), and institutions such as the Scottish city 'steamie' (communal washouse and informal meeting place for women) did a lot to help.
Poor working people did try to follow fashions, in a limited way, and display (often patronisingly called 'cheap finery') was important in all walks of life. But agree with earlier posters who said that fewer, better quality clothes were the norm because they were expected to last and therefore more economical in the long run - there is the old saying 'only the rich can afford cheap clothes'. As another poster said, clothes were often purchased second-hand, outgrown, out-of fashion or just part worn out, or passed on from one family member to another. It's often not realised just how important second-hand clothing was in the past - employers gave old clothes on to servants, rich people left fancy pieces to friends or favoured servants in their wills, parents' old clothes were cut down for children or stored away for their future use, children's clothes 'handed down', there were market stalls and pawnbrokers selling second hand clothes etc etc. And clothes were often stolen, for immediate use or re-sale.
Don't want to go on, but I think that the OP might also be touching on the whole issue of dress and decorum - what is considered appropriate, tasteful, modest, ladylike, classy, smart, normal and other very, very loaded words, which of course change their meaning over the years...
