Siegle has written a number of books including Green Living in the Urban Jungle (Green Books 2001), A Good Life (Guardian books, contributing author) and To Die For: is fashion wearing out the world? (Fourth Estate 2011).
Siegle's book, To Die For was nominated for the Orwell Prize 2012, is credited with being the go-to text on the modern day fashion industry's ecological and human footprint. It forms the basis of the 2015 documentary The True Cost, by director Andrew Morgan. Siegle appears in the movie and was one of the executive producers.

Siegle is credited with kickstarting and popularising the ethical fashion movement in the UK but is deeply critical of large fast fashion brands pretending to be ethical. She has said the whole UK movement is in danger of being co-opted and bought up by big brands and has been particularly critical of clothes recycling initiatives.

Together Firth and Siegle attended the 2011 Oscars to promote sustainable fashion and have worked on other events such as the Met Ball and the Golden Globes and BAFTAs.
