Apparel education
Most companies choose t-shirts backwards.
They start with the logo. The garment underneath decides whether anyone wears it.

Logo first, garment last
The typical merch order goes: pick a design, send it to a printer, choose the cheapest blank that comes in the right colour. The logo gets hours of attention; the garment gets none. Then people wear it once.
Flip it. Decide who wears it and when — a daily uniform, a weekend hoodie, an event tee — and let that decide fabric, weight, fit and finish. The logo goes on last, onto a garment someone already wants.
Five questions before you pick a tee
Who wears it, and would they choose it themselves?
How often is it washed, and at what temperature?
Does it need to look sharp (polo, wrinkle-free) or feel soft (special wash)?
Is it worn outdoors (UPF 50+, coolant) or indoors?
Will you reorder — and does the spec make month twelve match month one?
