Freya Response: Heather, we do keep a fair amount of space in this channel intentionally. This is to prevent constant stress on the ends of the channel where the wire ends, which results in the wire poking through after a period of time. The space you have described here in within our standards – we feel it is appropriate the extend the life of the bra and protect the $66 investment, and expect that it is the same wire and channel you will find in your basic Deco bras. We suggest sizing up in the cup (if the volume of your breasts will allow) in order to achieve the width in the wire you are seeking. Thank you! Heather from MA
