some patternmaking & sewing suggestions to help guide you through your first underwire experience
Step 1: breast basics
before getting started, it is useful to review some basic breast physiology. you may have your own method for brushing up on this, but to aid in your research at home, here are one or two facts:
+each breast is 90% water, can weigh 200/800 gms, sits on the chest wall between the 2nd and 6th rib,
+statistically, left breasts are often slightly larger than right ones, (up to 2 cup sizes!) though i encourage anyone to challenge this by submitting your own research on the topic.
+breasts have no internal support structure and rely almost totally on skin tension for their shape. this is where the bra comes in.
