I measure 32DD in La Senza and Ann Summers but measure 32E in M&S.
Ann Summers bras are gorgeous and comfy but expensive. Have got some lovely ones from Tesco and so much cheaper. La Senxa has loads of choice and you get clear straps with most bras and can change to racer back style or take straps off al together, they also have front fastening bras too. but 32DDs are getting too small and dont do 32E
