NEW YORK — Perry Ellis is not a brand that makes men nervous or causes them to titter.... ...Perry Ellis is not niche; it is mass. And its creative director, Michael Maccari designed a spring 2016 collection that was welcoming to a wide swath of men -----------.
Are "niche" and "mass" nouns here? How am I to understand them? Definitions I found for niche (recess in a wall, private space, habitat, ecological role) and for mass (liturgy, celebration of Eucharist, expanse, bulk, amount of material) do not seem to make sense here. How are these about clothing? Large clothes with much material? Clothes for church? Clothes for habitat? How are these opposites? ("is not niche. It is mass.)
What words could replace niche & mass to make this more understandable?
