My favorite body mod is HGEC but I love that BAB has a Imperial City shop that has a large selection of relatively lore friendly and non skimpy clothing. Is there anything like this shop for the HGEC body? I honestly haven't been able to find anything that has as good selection as the BAB store.

http://www.nexusmods.com/oblivion/mods/13437/? is an enormous HGEC shop, probably one of the largest (nearly 4 gigs) clothing mods ever made. Ten merchants sell items inside a multi-floor shop in the Waterfront District. It also comes with a companion mod: http://www.nexusmods.com/oblivion/mods/22962/? which offers clothes/armor/jewelry for both sixes in a store near Bruma.

I'll check it out but judgeing by the pictures on the mod page, there's going to be a metric ton of skimpy stuff to wade through before I find anything decent.

Sounds like any Mall or Department store in America

If this is set up like another clothing mod that I used back when, some merchants will have the skimpy stuff, some merchants will have the lore friendly stuff.
