The secondhand market is the truest test for fashion brands.

The secondhand market is not where you actively appear. But your products will end up there whether you like it or not: through resellers, online exchange groups, or weekend market stalls. At that point, the paper label has been cut, the paper bag has been discarded, and your Instagram page is no longer nearby to explain. The only thing left is the product itself. And the real question now is: looking at the product without packaging, can people tell who it belongs to?

Identity lives on advertising, not on the product.

Many Vietnamese fashion brands build their identity from the outside in: a beautiful logo on the website, a consistent Instagram feed, packaging that refines every detail. But when opened, the product inside is a neutral object, bearing no recognizable signs beyond the attached paper label. The identity lies in the wrapping, not in the core.

This is a structural issue, not an aesthetic one. Byron Sharp in How Brands Grow points out that identity assets only hold value when they appear consistently enough to form memories in the minds of buyers. That memory must be activated at the right moment of purchase. If the identity asset is only present in paid advertising but absent on the product itself, that activation chain is broken.

What does this figure mean for the secondhand market? Your products will circulate faster than ever, especially in the hands of Gen Z. The product lifecycle no longer ends with the first buyer. Each time it changes hands, your brand appears before a stranger, without accompanying advertising, without a story being retold.

Physical products are touchpoints that never fade away.

Wally Olins defines a brand operating through four vectors: product, environment, communication, and behavior. Most brand budgets are poured into the third vector. The first vector, the physical product, is often treated as a pure production requirement rather than a communication surface.

But the physical product is what lasts the longest. A shirt can be worn for three years, then resold and worn for another three years. Throughout that time, it interacts with more people than any advertising campaign. If the fabric, stitching, woven label, and finishing do not tell the brand story, you have wasted a cost-free communication channel.

A brand is not just a logo. A brand is the perception in the customer's mind.

Marty Neumeier, The Brand Gap

That perception is not formed through a logo on the packaging. It is formed through each accumulated touchpoint, including those that occur long after the packaging has disappeared.

The thrift store test actually checks what.

When Sinh Vũ works with clients on fashion identity systems, there is a simple exercise. Hold the product, assume all labels and packaging have been removed, and then ask: what remains that can still be recognized? For many brands, the answer is nothing.

This test examines the level of connection between visual identity and physical products. Jenni Romaniuk, in Building Distinctive Brand Assets, measures identity assets in two dimensions. One is awareness: how many people associate that asset with the brand. The other is exclusivity: how many people associate that asset with a single brand, not a competitor. A woven label is a potential asset in both dimensions if designed and maintained consistently for long enough.

The gap between 85% and 30% does not only occur on communication channels. It happens right in the production process: when the manufacturer changes the woven label supplier for a cheaper option, when the thread color is adjusted to match a new fabric batch, when the packaging changes each season without anyone paying attention to long-term consistency.

The physical details that last the longest.

Not all physical touchpoints have the same recognition value. Some things disappear immediately after unboxing, while others stay with the product until it is no longer used.

• The label woven inside the collar or hem: it exists throughout the product's lifecycle and is not cut unless intentionally.
• Border thread or distinctive decorative thread: visible from the outside, difficult to replicate in the low-price segment.
• The details of the stitching, the style of the zipper, or distinctive buttons create a unique "feel" even without visible labels.
• Decorative tags on the outside or embroidered patches: they last longer than paper tags and can become independent identity assets.
• Paper tags and packaging: only accompany the product to the first buyer.

The first four points are the most worthwhile investments in sustainable identity. Paper tags and packaging are important for the first purchase experience, but they do not create long-term identity assets.

From testing to specific actions.

Recognizing the problem does not mean having to redo the entire identity system. In many cases, the task is simply to review what is currently in place. From there, identify which physical touchpoints are creating recognition and which are missing opportunities.

A practical question for you to self-check: if you randomly take a product from the production line, remove all paper labels and packaging, and place it next to products from three competitors in similar conditions, can an outsider correctly identify which one is yours? If the answer is uncertain, that is the starting point for your next steps.

The secondhand market will continue to grow. Gen Z sees buying secondhand as a normal consumer behavior, not a temporary solution. This means your products will continue to circulate. They will keep appearing before people who have never heard of the brand, introducing themselves without any advertising budget. The question is: what are they saying?
