I'm a former professional T-Shirt designer. Here's a few pieces of advice for people thinking about doing something similar:
1. Reduce the size of the design - while it looks great on a flat t-shirt (and perfect for the promo picture) you need to add room for a human body at the sides (surprisingly more than you think). My rule of thumb is to measure from your left nipple to your right nipple. Try sticking printouts to your chest and you'll see what I mean. A logo could probably fit on a large post-it note (roughly the size of the of an iPhone).
2. You need to position the design so it floats in a woman's cleavage. The most popular t-shirt I did had a small duck that looked like it was sitting on a woman's chest.
3. Screen printed t-shirts are printed light-colour to dark colour (like an oil painting). If you put a full print of white under the other colours they will look more vibrant - even black. But remember that t-shirts have bleeds measured in mm! getting accurate registration on cloth is tricky.
4. Large designs with many layers of solid ink can get very sweaty to wear. Try to keep things small and have gaps in the design. The recent trend for grungy, worn & badly printed designs were naturally less sweaty.
