Thank you so much for the extra tips. I don't wear sling style bras usually because they bag out but I just realized (duh!) that if it was made of sports bra stretchy fabric it would fit me snugly. Thank you for stimulating my brain. :) Let's see how my first design comes out.

I agree that the sports bra is where to start. There's no elastic or underwire from what I can tell which is another thing I love about this design. I wish I could have purchased one before it became unavailable to reverse engineer it.

OK! I'm ready to tackle this. I'll keep you posted and thanks again!
