My favorite blend of Tee because it's oh-so-soft: 

[50% Polyester/25% Combed Ring-Spun Cotton/25% Rayon Jersey]

Colors Available: Vintage Black, Heather Grey, Vintage Navy, Vintage White

Design: Iron-On Vinyl Transfer - Recommended Care, see image below.

• IMPORTANT! - Sizing:  Women's tees are notoriously sized MUCH smaller than men's or unisex.  I would recommend choosing a size that is at least one size up but maybe even 2.   For example, I wear this style of shirt in an XL when I normally would choose a Medium so that it fits well in the chest and is still long enough.
