Yes, if you include other luxury brands as simply the big names, with big advertising budgets, like Dior, LV, YSL etc. etc. (those owned by Kering Group, Richmont, or LVMH. So yes, boutique chanel RTW and Hermes hand stitched leather (core strengths) as well as some less popular top tier RTW like Brunello Cuchinelli Cater to the same 1 %.
But, not all catergories within those brands are as high toned as some comparable speciality boutiques. For example, IMO only, my Hermes dishware seem far more mass produced than Hering Berlin. It’s silverware (I think it’s Pluiforcat) does not seem as nice as Georg Jensen. It’s furniture, formerly produced by Paltrona Frau, is not as nice as actually going to Paltrona Frau, and the furniture pales in comparison to, say, shopping for furniture at Galerie Philia etc etc. chanel bags, as their prices spiral higher, seem to aspire to cut out those who dont have large shopping budgets, but the bags aren’t hand stitched or of luxury exotic material. Hermes RTW is generally priced lower than Chanel, signaling, at least to me, that Hnis trying to attract a broader clientele.
There are arguably smaller more exclusive brands that also cater to the 1% segment. From my own shopping roster (along with my DH, who loves clothing) : bespoke tailoring, the most mainstream of which is bespoke haberdashery, such as turnbull and Asser and charvet. also, leffot, Duret, and the smaller trunk shows, for custom lasts for shoes etc. (Brunello also offers a trunk show experience to top customers where you can order items not available in boutiques and request custon bespoke.
The most boutique experience in watches and fine jewelry that I’ve come across is not Hermes (DH does have an Hermes H08) or Chanel, but Alange & Sohne (they do not advertise; they do not have mass produced women’s watches (like PP) or many diamond bezelled or jewlery options (like AP or breguet). Verdura belperron and Briony Raymond, perhaps for the charm of their ateliers, are the most 1% jewelry boutique experiences I’ve encountered.
The big name brands that are more mainstream, include Dior RTW; it’s a third to half the price of chanel. and is in the process of broadening its customer base with leather goods and youth oriented men’s collaborations. It’s menswear is relatively well priced so, it’s a bit more accessible. VCA, Bulgari, and Cartier, while extremely costly in the bigger one of pieces, do have popular more mainstream , well priced items.
if a luxury brand moves into cosmetics, sunglasses, IMO only, it signals to me, that they are trying to broaden their appeal.
Fragrance is a niche item that commands a lot of profit as well.
