Dressed to Invest: Why Your Wardrobe Might be Underperforming
Open your wardrobe and look past the three outfits you actually rotate. Behind them sits a graveyard of optimism – the going-out top still wearing its tags and the jeans that fit “once I get back into the gym”.
Congratulations, you're now managing an investment portfolio. And judging by the returns, you might want to fire the fund manager.
Think about it like an investor. Every item you buy is a position and its price is your capital outlay. Every time you wear it, the position pays a return, meaning an item that never leaves the hanger is capital locked up in an asset producing nothing at all.
Let’s do an audit.
Overdiversified, Underperforming
In finance, diversification means spreading your money across different assets so one bad bet doesn't sink you. Australians have taken this principle and applied it with incredible enthusiasm, ultimately confusing diversification with accumulation.
The average Australian buys 56 new clothing items a year, more than the US (53), the UK (33) or China (30), making us the world's biggest clothing consumers per capita. The average price per item is just $13, meaning it's not a portfolio, it’s just a very large number of very small bets (Australia Institute, 2024).
However, most of those bets aren’t paying off. A national RMIT survey found 84% of Australians own clothing they have not worn in the past year, and one in three has not worn more than half their wardrobe (Stock, 2024). Australians estimate they have an average of $1,226 of unworn clothing sitting in their wardrobes (Uber, 2025). In investing terms, that's $1,226 of dead capital. And that's before considering the opportunity cost: every dollar spent on clothes you never wear is a dollar that could have gone towards something you actually value. No dividends, no growth, just a slow depreciation into “maybe I'll wear it to a wedding”.
Cost-per-wear: the metric your wardrobe is missing
Investors don’t judge an asset by its price, but rather what it returns. Your wardrobe deserves the same treatment, and the metric is cost-per-wear.
Now let's run the numbers. A $13 top worn twice before it stretches or quietly disappears costs $6.50 per wear. A $120 pair of jeans worn 150 times over a few years costs $0.80 per wear. The "cheap” top is roughly eight times as much per wear. It just hides the cost better.
This is the fashion version of confusing price with value. The sticker price is only the entry cost, while the real return depends on how long you hold the position and how often it actually works for you. By that measure, the humble plain white tee you wear every week may be the best-performing asset in your entire portfolio. Warren Buffett would approve… probably.
Fast fashion is a high-frequency trade (and you are its counterparty)
High-frequency traders make money by placing enormous numbers of tiny trades, testing the market constantly, and cutting losers almost instantly. We can draw comparisons between this and how fast fashion works, using Zara as an example.
Zara’s owner, Inditex, describes its model as small production batches, constant changes to collections based on demand, and new designs arriving in stores twice a week. It was estimated that Zara produces over 11,000 distinct designs a year while most competitors manage 2,000 to 4,000 (Advergize, 2026). Zara isn’t literally a high-frequency trader, but its business model follows a recognisable principle: place small bets, respond quickly to market signals, and avoid getting stuck holding the losers.
The difference is who absorbs the risk. When a retailer tests a trend, its downside is one small batch. When you buy into that trend, you take the full position. The next collection drop is usually replaced within weeks, creating the familiar pressure to “buy before it’s gone”. Fast fashion accordingly manages its inventory risk by simply moving a fair chunk of it into your wardrobe.
Once the trend fades, the retailer has moved on. You're left holding the bag – quite literally
Why do we keep making bad trades?
If the numbers are this bad, why do we keep buying? It’s because the same behavioural biases that trip up investors also run our shopping carts.
Mental accounting: Richard Thaler showed that people sort money into mental buckets and treat them differently (Thaler, 1999). A $13 top doesn’t feel like real spending, where it instead lands in the “basically free” bucket, even though 56 of them a year add up to more than $700.
The Disposition effect (a.k.a the reluctance to realise investment losses): Rationally, what you paid shouldn’t affect whether you keep something. But, throwing out an unworn dress feels like admitting a loss, so it stays as a monument to a bad trade. Investors do the same thing when they hold a falling stock just to avoid locking in the loss.
Present bias: The dopamine hit of a new purchase arrives at the checkout but the regret arrives with the parcel. Our brains heavily favour the reward that turns up first.
Rebalancing the portfolio
The good news is that a badly run fund can be turned around. You don’t need to become a minimalist who owns four grey jumpers. You just need to stop impulse investing and start checking your returns.
First, run a portfolio review. Start with the pieces you no longer wear, want or need. Sell what still has resale value, donate what's in good condition, and consider repairing what you already own. Liquidating recovers some capital and frees up space for things that actually work.
Second, buy fewer, higher-conviction positions. Before checkout, ask “will I realistically get enough wear out of this item?” If not, it’s a speculative punt, not an investment.
Third, think like an index fund. The best-performing wardrobes, like the best-performing portfolios, tend to be boring. Reliable basics that go with everything deliver steady returns, while trend pieces behave like meme stocks; exciting on day one, forgotten by week three.
So, should you fire your fund manager?
Your wardrobe isn’t a disaster, it’s just being managed on vibes instead of fundamentals.
The solution isn't to stop shopping altogether, but to start thinking like an investor. Judge your purchases by cost-per-wear rather than sticker price, cut your losses, and stop treating every new trend like the next big investment opportunity.
And if your portfolio is still underperforming? Unfortunately, there's only one fund manager to blame. It's us.
Until next time,
