Go for something plain and understated in terms of clothing. White shirt, black skinnies, high heels... maybe a string of pearls and a thin stroke of liner and blush. Grey and an allblack ensemble would look tres chic as well... even a neutral beigy-tan top. Stay away from oranges, corals, pinks, and reds in clothing. Red nails and lips are a big no-no and a bit much too, especially if the two shades arent exact.
Whatever you wear, im sure you'll pull it off
Just make sure you get the best shade of red for your complexion and tone
