We usually wear clothes over our dipes too. I've just switched over our stash, so it's mostly pockets again (that's how we originally started). FB's are pretty trim (depending on inserts) so are HH and Drybees. We use prefolds and covers too, but for us, those tend to be on the bulkier side.
We did have bG! at one point and I remember that being really trim. It just didn't work for ds though.
