Radha herself won't be releasing any more lines - when a new artist revamps an older artists SBQ line, we don't take it over, we just bring that one set up to date and then it's left again.
That being said, I would absolutely love to have some more diversity in our high fashions. Your examples here are lovely! It can be problematic for us to borrow ideas from other cultures, there is the risk of unintentionally being offensive in ways that our google searching didn't let us in on. But we'll do our best :)
(At the very least, Giselle has something coming up that has influences from Arabian culture...)
