Combining the ideas of both posts:
You can spend less if you buy more targeted-to-you and higher-quality items that you'll wear more often. Finding these items and customers is a data (and marketing) problem.
E.g. I spend less overall than I did a few years ago but each item I buy is more expensive. I've learned the value in quality clothes. I give smaller batches of more money to well-picked retailers rather than lots of small batches of money to big-name mass-market retailers.
An app that capitalizes on people coming to this realization (and knows how to market and execute it well) could make a killing.
