Simone Perele Response: Thank you for your feedback. We are pleased to know you appreciate the quality of our Brand. Given your feedback, that the arc is too narrow, I would recommend trying a 34 band. Typically when the wire cuts in and digs under the arm, the band is too tight. We do not recommend ever bending our wires. Although they are flexible (to provide maximum comfort), trying a different size, in your case a 34C for this bra, should eliminate the dig you currently feel.
