Warner's Women's Cloud 9 Super Soft Underwire Lightly Lined T-Shirt Bra Rb1691a

i'm looking for warners style #01593. is it still available?

Is the white on really 80% nylon or is it 88% polyester?

Are there any RB1691 that aren't shiny?

Are the back strap and hook pieces soft? Lately, every bra I've tried (at least 20) are itchy across the back. Like they are sewn with wire.
