difference in fabric according to color

I had ordered this same bra in black a few months ago and it is the perfect bra for ladies that need support and pushup, nothing will fall out or move. Ordered this same one in cream/nude just recently and theres def a difference in fabric and feel between those two colors. The cream bra is even a tad looser on the top, thing that does not happen with the black. Just in case, I get professionally measured before a bra purchase when a lot of time has passed so I did get the right size. Above all, the bra still fits very well but I suggest buy the black one.
