Good day, do playtex wireless bras comes with padded cups to enhance my girls?

Playtex product # 4159 is not padded. I love that it’s not because so many bras are. I’m a double D and don’t need more! This bra is so comfortable and love that it has the support I need without underwiring!

is this the #4159 playtex bra??

Yes. I see the number 4159 on the end of the tag.

I wear a 42dd but the band slips up, would a 40dd be better?

If you're on the tightest set of hooks already, yeah, a 40 might be better. However...a 42dd equates to a 40ddd on cup size. Bra sizes are weird. A DD cup isn't the same size across the board. For example, roughly speaking, a 36DDD is a 38DD or a 40D (ignoring the fact that the straps shift position on your body as you change band sizes and might be less comfortable). BUT if the cup fits well, you might consider taking a small tuck into the back of the 42 band on either side of your spine to snug it up a bit if you're even passable with a needle and thread. Best of luck to you!

is the cup show nipples, is it dbl lined?

It doesn’t on me... it isn’t double lined, but the fabric is pretty thick. Hard to explain, but I really like this bra. I’m older and not interested in showing anything!
