About this app
747 is the offline lifestyle companion for adults attending formal evenings — galas, charity balls, opera premieres, weddings, embassy receptions, awards nights, debutante balls, and casino-themed evenings.
It tells you exactly what to wear, what to bring, and how to behave — without an account, without a network connection, and without ever asking you for your data.
Five dress codes, both ladies and gents
• Cocktail, Black-Tie, Creative Black-Tie, White-Tie, and Morning Suit — each documented in detail for both ladies and gents
• Illustrated fashion plates show the cut, fabric, and silhouette
• Footwear, accessories, and region notes (US / UK / EU phrasing) for each code
• A clear "what to wear" and "what to avoid" list so the rules are obvious
Eight occasion guides
• Gala, Casino Night, Opera Premiere, Charity Ball, Embassy Reception, Formal Wedding, Awards Night, Debutante Ball
• Each occasion explains the recommended dress code, the etiquette of arrival, the table manners, the toasting protocol, and how to leave with grace
• Five conversation starters per occasion so the small talk is never awkward
• Plan an event with one tap and Grand Style pre-fills the dress code and prep checklist
An outfit picker that does the thinking for you
• One tap on Randomize and 747 picks a formality, a color palette, an accent piece, an accessory, and a grooming tip
• Lock the elements you like and re-roll the rest
• A history of past picks so you can revisit a look you loved
Event calendar with prep reminders
• Log an upcoming event and 747ph builds an automatic checklist — dry-clean by D-7, shoe shine by D-5, hair appointment by D-2, final try-on by D-1
• Optional local reminders so nothing gets forgotten
• Link wardrobe items to an event so the look is ready before you leave
A wardrobe that works for you
• Catalogue your tuxedos, gowns, shoes, jewelry, clutches, cufflinks, and ties
• Photograph each piece or pick a category icon
• Grand Style suggests a complete outfit for any upcoming event from your own wardrobe
A small knowledge base for the moments that matter
• Pearls vs Diamonds, Watch Styles by Occasion, Bow Tie vs Necktie, Pocket Square folds
• Glove etiquette, table seating, toasting protocol, posture and carriage
• Twelve illustrated cards on etiquette, jewelry, dancing, and toasting
Built to respect your privacy
• Fully offline — no account, no network calls, no analytics
• Photos and event details stay on your device
• Local notifications are opt-in and can be turned off at any time
Whether the invitation says Black-Tie, White-Tie, or simply "formal evening," Grand Style gives you the answers you need before you reach for the phone.
Dress for the moment.
