Chantelle Response: Thank you for your feedback. Is sounds like you might be wearing the incorrect bra size. Please consider going up a cup size.

The horizontal seam on this classic style is used to help lift and support the breast tissue. We would suggest trying Chantelle Rive Gauche 3281
3 part cup which has a flat transversal seam which offers a rounded shape with no seam show through. Other Chantelle styles that offer this flatter seam are 3371, 3651, 3991, 3946 and 3851.
