The jacket and pants are both navy blue, I said jacket and pants bit redudantly but its a suit, it oughta be cost me over 600 euros

Already have plently of white shirts (and red tie), prefered dark red shirt this time, without a tie. Have brown belts, but will wear a black one instead, to match with the black shoes (which are much nicer then the brown shoes I have).
And nah, I'm adamant about no tie this time, as I said, casual affair/party evening so gonna skip tie or bowtie this time.
Do you have snapchat? You sound like you are better adviser then the 3-4 friends I was sending pics to in snapchat while shopping
