design help with legs on piesafe/pantry

I’ve been working for quite a while now on this large pantry-ish piece (I’d call it a pie safe, except that the doors are frame-and-panel wood rather than tin with holes). I decided to build the carcase out of four solid pieces, yellow birch for the sides and white pine for the top and bottom that don’t get seen. The pieces are joined by dovetails (see picture of the bottom – the scerws are there to attach the sliders for the drawers and are not structural).
I’m looking for advise on choosing and attaching legs. The lines of the piece are pretty undecorated (as you can see, although there will be crown molding on the top) so I’d kind of like to put simple tapered straight legs in the four corners, about 8 inches high. But I can’t figure out how to attach them. Any ideas?
Thanks,
JH
