I feel like the “one brand for the rest of your life” part of the ask is being overlooked. Sure, for work and day-to-day stuff a lot of brands cover those bases. But what about wedding attire? What about any sort of suiting? All seasons? Something you can wear today and still want to wear in ten, twenty, thirty years? There’s a long term strategic game to consider. For luxury it’s easy to go for whatever is hyper popular now, but you’ll look silly wearing some of these brands in your 70’s. Think timeless and versatile, think about the collabs the brand does that cross into other life tasks. I think Drakes is one of the best at hitting every single season, every situation. The other only answer I can think of that might not fall under typical luxury is Ralph Lauren with the massive umbrella of sub-brands.
