That is from BoobDesign.com and it's a $79 tshirt. Yes, you read that correctly. Seventy nine dollars for a TSHIRT. If you want to buy the shirt instead of making your own, head right on over to http://shop.boobdesign.com/en/product/344/nursing-v-neck-before-after. I love their stuff, but it's a bit too rich for my blood. If you want to learn how to make your own shirt... keep on reading.
Works like a charm!
