Categorization is a double-edge sword. One one hand, it's useful for organization and classification to help better navigate a large market (or a large collection for that matter), but on the other hand, can lead to weird flexes a la social classism like "I only wear the finest niche fragrances" and then all the associated hubris. It's always a tricky balance to use categories as tools to help understand the kind of variety you have rather than becoming an enormous tool when you insist on assigning value sight unseen based on a preconceived notions of classification.
Also, current terms are really vague and inadequate, but used because they have become something of a standard practice in the community.
I use the following:
Drugstore/Consumer Brand: The basic or entry-level fragrances found in drugstores, supermarkets, large "big box" retailers like Wal-Mart, and are typically made up of legacy brands, grooming brands, lower-tier celebrity or licensed brands, and "fallen" designer brands that have hit downmarket distribution and price points that make them equivalent to others in the category. Coty, Revlon, Claiborne, Bogart, Jovan, Antonio Banderas, and Addidas all qualify. Direct-selling or MLM brands like Avon, Oriflame, Jafra, Armand Dupree, and Mary-Kay also get this category because even though they are not sold in stores, they have similar price points and availability. Typically not discussed by enthusiasts or seen as below a standard baseline worth exploring but viewed fondly or with nostalgia by everyday people and folks specifically into old pop culture kitsch and wet shaving. Also can include commonly-found fragrance mall chains like L'Occitane, The Body Shop, or Bath & Body Works. Between $10-$69 usually
Mainstream Designer/Boutique Brand: Stuff too expensive for the big boxes, but too common for the ultra high-end retailers like Bergdorfs, Harrods, Le Bon Marche, and the like. Brands like Chanel, Dior, YSL and such. Most of your luxury department stores will handle these brands as they are designer brands, but they also get heavily discounted elsewhere like Ross or online perfume sellers such as FragranceX. If not sold in department stores, they'll often be sold in boutiques associated with the designer, like Express, Zara, Victoria Secret, or are licensed from brands that aren't designers technically, like Montblanc, Cartier, Tiffany, Bvlgari, Lalique, and the sort. Can also include more expensive boutique lines like Art of Shaving and higher-ranked celebrity or licensed brands like Sarah Jessica Parker or Bentley. Tends to be the bulk of enthusiast discussion where compliments and social proof are points of merit (i.e. Fragrantica), but not among "connoisseurs", since styles tend to be analogous to trends and many options are variations on a single theme. Ranges from $70-$129 usually
Designer Exclusive/Luxury/Niche: Classic French houses that were once considered dispensaries of luxury fit this bill, like Guerlain, Caron, Houbigant, D'Orsay, and the like. Exclusive/expensive designer lines like private lines from Chanel and Dior, or the entirety of perfume lines from Tom Ford or Louis Vuitton also make this grade, as do self-appointed luxury perfumers like Creed, Roja Dove, Amouage, Parfums de Marly, Bond. No 9, and House of SIllage. Niche brands as self-identified, offering mostly if only perfumes, and having tighter distribution, often more artistic free-license, or some marketing gimmick also meet this criteria. These include L'Artisan Parfumeur, Diptyque, Jo Malone, Byredo, Maison Francis Kurkdjian, or Juliet Has a Gun. Tends to be the bulk of discussion among enthusiasts looking for status like "fragbros", or "perfume journey" types into artistic merit and explorations of emotion/personality over mass-appeal (i.e. Basenotes). Price points versus value are hotly contended, and many also end up in discounters too. Ranges from $130-$1000+
Artisinal/Indie/DIY: Total Wild West of perfumery. No ingredient restrictions, no method standardization, no accreditation among perfumers, but also total creative freedom. Often frustratingly small, single-run semi-bespoke fragrances that will never be bottled again after selling out and can be prone to quick degradation if all-natural. Huge cause of FOMO frenzy from small fervent fanbases and prone to ridiculous gouging more than other types of limited or exclusive perfumes for this reason. Oftentimes focus is rarity or origin of ingredients over skill or style of perfumer, and sometimes perfumes are something other than alcohol/water based, being oil roll-ons or attars. Typically the "journey's end" for enthusiasts looking for presumable the most "natural smelling" perfumes or the ultimate in exclusivity, walling up like "comic book guy" in groups or threads dedicated to their favorite perfumers, but hotly contentious for everyone else outside these circles. These fragrance also tend to have "sequels" if subsequent batches are made. Price floats around $100-$800
Clone Houses: These brands sorta exist both outside and within all the other genres, as they range from outright bootlegs to more-honest "our version of" fragrances like Classic Match or Jordache that mimic styles set down by popular mainstream brands like designers, to more uniquely-packaged brands that have a modicum of concern for quality, and seek to create offerings that equate to alternatives rather than imitations of what they "clone" Sometimes in the latter case, this is because brands popular in some areas may be nigh-inaccessible in others, like the Middle Eastern houses that specialize in making takes on Western fragrances such as Rasasi, Al Haramain, Armaf, and the like. Still there are other almost niche-like clone houses like Dua, Alexandria, or Pineapple Vintage that try to clone hyped batches of fragrances where reformulations have occurred, or hyped discontinued fragrances where someone might settle for a clone, These rarely get discussed unless the clones are alternatives to something prohibitively expensive like a luxury niche scent or a discontinued fragrance selling for a high price, and themselves can vary from $10 or less to over $150.
Bonus Category - The Vintage Fragrance: Since a separate community has grown in the past 10 to 15 years concerned only with discontinued perfumes or fragrances made prior to IFRA materials restrictions or in some cases before an arbitrary cutoff (launched before 19XX or 20XX), this category has come into being. Vintage fragrances can be discontinued lines or whole brands from other categories, or be extant older batches of currently-made fragrances where enough difference in smell is claimed to make erstwhile formulas different perfumes altogether (aka "shadow of its former self" syndrome). Seemingly fragrances regardless of launch get sucked into this category if discontinued or reformulated, because the fact they're discontinued or reformulated alone gives enough merit to become valid for vintage enthusiasts, who like artisanal fans will often stick to their own spaces and not entertain anything outside of them. Prices are all aftermarket and run from $1-$1000+
Funny, after writing all that out, I sorta feel like these terms almost better fit the kind of people these fragrances appeal to than the fragrances themselves, unless you're a filthy infidel like me that plays fast and loose with all the categories simultaneously. They don't have a category for heathens like me, just usually a bouncer waiting to escort me out.
This is pretty precise.
