If you’re doing to do it, do it properly I’d say; poor black tie looks worse than a smart lounge suit.
Black Tie:
Single-breasted (more formal) or double-breasted (less formal) Black jacket with silk/satin/grosgrain facings
Peak lapel (more formal) or shawl lapel (slightly less formal). Notched lapel is naff.
White pique marcella shirt with studs or concealed buttons with a regular collar (Wing collars are for white tie only in the UK; don’t be a pleb)
Cufflinks to match your studs if you have them, preferably gold colour.
Cuffs should not be visible from under your jacket.
Waistcoat (U-shape or backless) or cummerbund. Neither worn with a double breasted jacket.
Patent leather balmoral, oxford or court pump/shoe.
And for heaven’s sake don’t call it a “Tux” or even Tuxedo.
