Top 3 Best-Selling Merch T-Shirts of 17 October 2025

Every day, thousands of new designs hit Amazon Merch. Yet only a few manage to stand out and sell consistently. Here are three shirts that are performing strongly right now, based on verified listings and Amazon’s own “bought in past month” data.

1. KPop Demon Hunters Halloween Huntrix T-Shirt

This officially licensed design has been a huge hit during the Halloween season. Similar listings show over 30,000 units bought in the past month, confirming its popularity among anime and K-pop fans.

KPop Demon Hunters designs often trend during seasonal events. Staying aware of upcoming releases or movie tie-ins can help creators time their designs better.

2. No Kings Protest Sign Vertical T-Shirt

This minimalist political design has gained steady attention online. On Amazon, “No Kings” versions show 300+ bought in the past month, suggesting stable niche demand rather than viral sales.

3. Dr. Seuss Thing 1 Emblem T-Shirt

A classic that never fades. Licensed Dr. Seuss merchandise, especially the Thing 1/Thing 2 designs, continues to move thousands of units each month. Current data shows about 6,000 sales in the past month across verified listings.

Smart Takeaways for Merch Sellers

Understand royalties correctly: Amazon pays a fixed royalty per sale, not a flat percentage. For a $19.99 shirt, you earn about $5.23 after Amazon’s costs.

Don’t rely on exact rank numbers: Category ranks change hourly. Focus on designs with proven demand signals like “bought in past month.”

Balance your portfolio: A healthy mix might look like:

Design for clarity: Keep text readable at thumbnail size. Simple artwork often converts better than over-detailed illustrations.

Price wisely: $17.99–$19.99 remains the sweet spot for impulse buys.

Final Thoughts

High-volume shirts like KPop Demon Hunters prove that timing and niche appeal matter. Steady performers like Dr. Seuss and simple protest designs show that consistent sales don’t always come from trends—they come from clarity and connection.

Success on Merch isn’t just about chasing what’s hot. It’s about understanding what people actually wear and why.
