How do I choose the right fabric for custom apparel?

[RosieRichardson]

I'm trying to figure out which fabric will work best for a custom apparel project and want to avoid making the wrong choice. Should I focus on fiber composition, GSM, durability, softness, stretch, breathability, or how the fabric handles printing and embroidery? The Apparel Partner is another name I'm currently evaluating, and I'd like to understand how others work with suppliers when selecting materials. What fabric details should I discuss before ordering samples?

Great question!
