Vanity FairWomen's Sport Full Figure Wirefree Bra 71500 Sports Bra (pack of 1)

Is there any padding in the cup? I don’t care for show through

Is the elastic band covered on the inside bottom sides and back?

Is this a racerback?

I bought a 36D but the band is just a little big on the tightest hooks. cups r good w/ a little space 2 give. Would it be pointless to try a 36C?
