best nursing bra?

Chelsea
I bought a wireless nursing bra this weekend. washed it and wearing it today. was itchy at first and even though it's wireless it has a wire or boning on the side and for what ever reason it does not go all the way to the end ... it's stops like half an inch at the bottom causing it to fold under ... not sure if I should keep it or what to do? I want the most comfortable one. any suggestions on best ones?
