The best pant color for the black blazer in our opinion is gray.
For some, a higher contrast white shirt on a blue blazer will highlight your features.
Black and pink creates a start contrast that will overpower almost any wearer since black makes any saturated color look really strong.
Hi, am a 48 yrs man with height of 168cms, weight around 68 kg, black hair, brown near to black eyes, skin color Tan.
It is closer to light gray, so it is a bit more feminine than pure white, and shows a sense of casual fashion and high-end.
However, if you go with the mentioned ideas about grey jeans, you are never going to say again that you do not love grey.
Grey is a versatile color that can match with almost any other color.
Your best best, Naveen is to put both outfits on and look in the mirror at each and decide from there.
