Eveningwear: gowns and tuxedos, full stop.
White tie is the most formal Western dress code: a black tailcoat with matching trousers, a white marcella waistcoat and bow tie, and for women a full-length ball gown.
Black tie is formal eveningwear: for men a black tuxedo with a black bow tie, for women a floor-length gown or an elegant tea-length cocktail dress.
Morning dress is the formal daytime code built around a black tailcoat with striped trousers — the classic silhouette at British royal weddings and high-formal morning ceremonies.
Creative black tie keeps the black-tie silhouette — tuxedo, gown — but invites personality: color, texture, statement accessories.
The step just under black tie — floor length or a dark suit.
Black tie optional (also black tie invited or black tie welcome) means the host is wearing black tie and you may too, but a formal dark suit or an elegant evening dress is fully acceptable.
Formal attire on an invitation means the step just below black tie: a dark suit and tie for men (a tuxedo is welcome but not required) and a floor-length or elegant midi dress for women.
Business formal is the top of the office dress code ladder: a dark, impeccably tailored suit; a crisp white or pale shirt; conservative accessories; and nothing that could be mistaken for Friday.
Lounge suit is the British invitation phrase for a regular business suit — jacket and trousers in the same cloth, with a shirt and tie.
Party clothes with polish: knee-length dresses, suits with character.
Cocktail attire is polished party dress: a dark suit (tie optional) for men and a knee-length or midi cocktail dress, or a chic separates look, for women.
Festive attire is the dress code with a celebration clause: take the event's base formality — usually cocktail or semi-formal — and add sparkle, color, or holiday texture.
Dressed up but breathing: day suits, midi dresses, relaxed tailoring.
Beach formal sounds like a contradiction and is really a negotiation: formal-event polish executed in beach-proof materials.
Business attire is the professional standard: a matching suit in a conservative color with a pressed shirt, and for women a suit, a dress with a blazer, or tailored separates.
Dark suit (sometimes "dark suit, no tie needed") is the modern American wedding code sitting just under semi-formal: a navy or charcoal suit, dress shirt, and a tie that is welcome but optional.
Semi-formal is dressed-up but breathing: a suit and tie for men (color allowed), a midi or knee-length dress or a tailored jumpsuit for women.
Collar, structure and clean shoes — denim allowed if it behaves.
Dressy casual is smart casual's evening cousin: the comfort of casual pieces elevated by fabric and fit — a silk blouse instead of a tee, dark straight jeans instead of chinos, heeled boots instead of sneakers.
Garden attire is cocktail or semi-formal dressed for grass and weather: lighter fabrics, block heels or wedges instead of stilettos, and colors that flatter an outdoor palette.
Resort attire (resort casual or resort elegance) is warm-weather polish for destination events and cruises: breathable fabrics, relaxed tailoring, and sandal-adjacent footwear — with the evening version, resort elegant, asking you to upgrade the fabric rather than add the tie.
Smart casual is the deliberate middle: structured pieces — a blazer, a collared shirt, dark denim or chinos, clean leather shoes — worn with the ease of casual dressing.
Business casual is the office code without the suit: chinos or tailored trousers with a collared shirt or fine knit, and for women the same range plus skirts and dresses.
Whatever is clean and deliberate; effort matters more than category.
Casual on an invitation does not mean whatever-you-want; it means relaxed but deliberate — clean, well-fitting everyday clothes with no holes and no apology.
Armoiria catalogs what you own and builds the outfit for the code — so the invitation never wins.
