Likely because your conception of "tasteful" is not neutral or objective, but rather shaped by our shared understanding of social class and status. Black attire is more visible and culturally salient in urban, cosmopolitan centers such as New York City, rather than suburban or rural locales. Additionally, it's popularly associated with certain members of the creative class.
Those people wear black partly because the color plays well in gray urban environments and fits in with local scenes, allowing them to look good while signaling belonging and identity. Plus, the history of the color — from its role in mourning wear, judicial robes, formal attire, and motorcycle jackets — makes us associate it with seriousness, power, rebellion, mystery, elegance, authority, discipline, and even seduction.
Thus, your conception of tasteful is shaped by social dynamics, and people wear black because clothing is imbued with cultural meaning shaped by history.
In a September 2000 interview with The New York Times, Japanese fashion designer Yohji Yamamoto — who wears all-black outfits better than most — said this of his favorite color:
"Why black? Black is modest and arrogant at the same time. Black is lazy and easy — but mysterious. It means that many things go together, yet it takes different aspects in many fabrics. You need black to have a silhouette. Black can swallow light, or make things look sharp. But above all black says this: 'I don't bother you — don't bother me!'"
@nunopgpalma_pt@AndreCVentura Como é que pode ter a certeza que não é uma ameaça à democracia? Não estou a ser irónica. Estou genuinamente interessada na sua resposta
@AndreCVentura Ahahah quais são as soluções do Chega? Um discurso de troglodita, cheio de falácias e chavões, que apela aos instintos mais básicos do ser humano. O PS não é a solução mas o Chega nem sequer consegue debater soluções de forma lógica, sustentada ou civilizada.
@pedroml Ahah decidir entre a extrema direita e uma bolacha de água e sal. O pessoal escolhe a bolacha, que remédio. Zero de entusiasmo. É este país que queremos?!
