See Fitter's Comments below for hook count. Please Note: Elila has unique bra sizing. We recommend adding 3-4" to your rib cage measurement. So if you measure 33", you would start with a 36 band size. For band sizes 36 and up, you should go up a band size and down 2 cup sizes. (e.g. 36I(D6) would try a 38G(D4)).
