The Lycanthropos http://www.daz3d.com/i/3d-models/0/night-world-lycanthropos?item=7542&cat=&_m=d at DAZ does have some clothing sets, one of which is a zoot suit :)  http://www.daz3d.com/i/shop/reqlist?item=7542&_m=d
Also, WardrobeWizard2 (a clothing converter) also supports the Lycanthropos via an add-on pack thus opening up a whole range of clothing.

Sanctum Arts' Horde creature (currently on sale at ContentParadise http://www.contentparadise.com/us/user/rd_phenotypes_011_horde_product_43039 ) also has a bodysuit available at ContentParadise http://www.contentparadise.com/us/user/ms_horde_sci_fi_suit_product_45988  .

Hope that helps some.
