No, the label is not GOD as if divine beling.
It is G-O-D. which is (kindof) a fast English way to pronounce a Hong Kong phrase meaning "better living". GOD is mainly a lifestyle store and sells furniture and all sorts of stuff.
And no, this is NOT the Hong Kong streetstyle nor Hong Kong "fashion". Most people who actually buy clothings from G-O-D are foreigners visiting Hong Kong.
I like some of their design, they are playful and kitsch and kind of silly. They took much of the unique Hong Kong scenes, and I like that.
