The trend lifecycle: when to buy in and when to walk away
Fashion trends move through a predictable five-stage lifecycle. Knowing which stage a trend is in tells you both what to pay and whether to pay at all.
Stage 1: Runway (year zero)
The look exists only in designer collections and editorial shoots. Prices are extreme, availability tiny. Buying here is for people whose job or joy is fashion itself. For everyone else: watch, note what keeps reappearing across multiple designers - recurrence across houses is the real signal - and wait.
Stage 2: Early adopters (months 6-18)
The look hits premium high-street and contemporary brands. This is the highest-risk entry: you pay near-full price for something that might die here. Only buy at this stage if the trend passes the wardrobe test - it works with at least three things you already own and fills a slot you actually have.
Stage 3: Peak (year 2)
Every retailer has a version. The paradox: this is the best time to buy and the moment it starts feeling common. Quality versions exist at every price, competition has driven real options, and resale value still exists. For wardrobe-relevant trends (a silhouette, a coat shape), peak is exactly when to buy well.
Stage 4: Discount (year 3)
The trend floods clearance. Two sub-rules: classics-in-trend (a camel coat during camel year) are smart discount buys; novelty-in-trend (the extreme version) is a trap - you will wear it twice.
Stage 5: Thrift (year 4+)
The trend is 'out', which is when the genuinely good versions cost nothing secondhand. If you loved it, this is your moment - personal style is precisely the confidence to wear things after the cycle moves on.
The summary rule
Buy classics at peak or discount, trends at thrift or not at all. The only losing move is novelty at full price.
