Text-Based T-Shirt Designs For Seniors

I already have a basic Shopify store online with Razorpay connected and a custom domain in place. Before I begin driving traffic, I need two things from you:

First, a quick but meaningful bit of research that confirms the best sub-niches inside the senior market for text-only tees (fun retirement quotes, health-positive slogans, age-proud one-liners, etc.). I’m not asking for a full MBA-level report—just enough data and competitor insight for me to launch confidently and keep the store trustworthy.

Second, a starter collection of original, text-based t-shirt designs aimed squarely at seniors. Clean typography, legible at a glance, and print-ready transparent PNGs are essential. If you can show me past work with similar typographic apparel, that will carry the most weight in my decision.

My budget is very tight, so please be realistic about what you can deliver quickly. The sooner we can push the first designs live, the better.
