is a brown dress with a hat and a navy blazer TAN with cream pants clash? Is the color combination to work?
I wear a dress with ruffle chocolate brown boots and a cream hat couture for a wedding. The required attire for men is a navy blazer and pants cream. If the brown and navy clash?

Technically they are both neutrals so you should be fine.
Would never have been my choice of colors, but it should be okay – that corresponds to the tan brown, I guess. Navy is a little more neutral, but. . . . they should have less color chosen for the wedding celebration! Tan & White is more beautiful, or Marine & White. . .
Wait, you wear the jacket and pants? If your man is wearing, that you bear and the dress and hat. . . it will fit well. If your planning on anything to wear. . . . . I do not recommend wearing all these layers. Plz pick me for best answer.
