newstalgia noun [U]
UK /njuːz.ˈtæl.dʒə/ US /nuːzˈtæl.dʒə/
a trend where old and new ideas and styles are combined to create a comforting, familiar mood that is also up to date and modern

Here’s the thing: brands that win today aren’t just forward-looking—they know when to look back, too. Enter newstalgia: the trend that’s revamping yesterday’s icons to make today’s headlines. While classic nostalgia tries to recreate the past, newstalgia flips it, remixes it, and gives it edge. This is how brands stay culturally relevant, and Gen Z is here for it.

boom boom noun [U]
/ˈbuːm ˌbuːm/
a trend in fashion and culture that suggests wealth, glamour and confidence, often inspired by similar trends of the 1980s

Boom boom is glamour and greed, epitomised by a style and mindset reminiscent of the sleazy, money-saturated world of late 80s New York. There is an end-of-empire, end-of-history nihilism to it, a sense of raising another bottle of Moët into the air while the world burns around you. But it’s also about aspiration, panic and the jarring disconnection between the economic climate we want and the one that exists – an experience shared by most.
