5 Easy T-Shirt Ideas That Actually Make Money 2025!

About this video

The creator presents five low-competition t-shirt niches he says are actually selling, found using Amazon search data, manual digging and research tools such as Merch Informer, filtering out overdone, copyrighted or trademarked ideas. The creator reports having sold over $500,000 in royalties all time and over 125,000 products. The niches are: (1) vintage Rome / gold vintage Rome souvenir designs featuring the Colosseum and Italian landmarks, extendable to other cities and landmarks, supported by low result counts, ratings and ‘bought in past month’ and BSR signals; (2) patriotic Boston Terrier dog with an American flag and sunglasses, described as evergreen but stronger around holidays such as the Fourth of July; (3) a one-foot Bigfoot design playing on amputee recovery, a humorous, relatable concept for amputees; (4) golden retriever in western cowboy style, including desert, cactus and cowboy-hat imagery; and (5) ‘mom of the birthday duck,’ which should be scaled into a full matching family lineup (dad, brother, sister, aunt, grandparents) under one brand so families buy multiple shirts. For each niche he shows an Ideogram AI prompt and generated options, advising creators to let AI do about 80% of the work, take individual elements, iterate, and always double-check trademarks and copyrights. He also promotes his weekly research vault offering 20 low-competition niches per week.

Key takeaways

• Validate niches with Amazon signals such as low result counts, BSR, ratings and recent purchases, rather than uploading untested designs
• Five niches covered: vintage Rome souvenirs, patriotic Boston Terrier, one-foot Bigfoot amputee humor, western cowboy golden retriever, and birthday duck family shirts
• Extend a winning concept sideways: souvenir designs to other cities/landmarks, and birthday designs to a full matching family lineup
• Use AI image prompts to generate design options quickly, but iterate, extract elements, and add human judgment
• Always double-check for trademarks and copyrights before using any niche or design, and avoid famous-brand designs
