I’m really sad as a Millennial that this aesthetic has been dubbed “Millennial gray.” I’ve watched some videos on it that make the case that it’s a backlash from the 70s aesthetic we grew up with combined with poor financial prospects in early adulthood, meaning we couldn’t buy a lot of or very nice furniture. Now that I’m firmly middle-aged, I can afford better stuff and my husband and I are slowly turning over crap particle-board furniture for nice solid wood pieces (often secondhand) in the craftsman style.
