Should I buy inventory based on personal taste or sales data?

This is one of the most common tensions boutique owners face: your favorite pieces aren't always your bestsellers. One boutique owner discovered that seven of her top ten SKUs were plain solid tees she found boring to sell — but they flew off the shelves. The exercise that reveals this is simple: make two columns labeled 'I'd Wear This' and 'This Actually Sells,' then compare the overlap.

The resolution is to let the register decide your reorder depth. Buy one unit of something you love to keep your store's personality and creative vision intact. Buy twelve units of what the data proves your customers want. Your personal taste gets expressed in curation, styling, content creation, and the experience of walking into a beautifully merchandised space — it just shouldn't dictate how many units you order.

This also applies to ad creative. Many boutiques run aspirational lifestyle shots of new arrivals while their actual proven bestsellers aren't featured in any active campaign. Point your ad dollars at the validated winners first.
