the Modeling with Littlefox series is very good (you have to get it at DAZ now, wait till it's on sale). Also Lyrra Madril's: https://www.renderosity.com/mod/bcs/how-to-make-clothing-for-poser-a-step-by-step-guide/112346/

Littlefox uses Modo, Lyrra uses C4D. I like these because they take you from nada to finished: modeling, grouping, boning and rigging all in 1 place without having to hunt around for the next tutorial you need.
