This is straight off of the FAQ for Breast Actives. I hope it helps
What is the most effective way to measure the growth of my breast?
In clinical studies, women are instructed to buy a test bra that has a snug fit. This bra is not to be worn on a daily basis (improved breast size would result in a stretching of the bra if worn on a daily basis). Every 2-3 weeks the women are then instructed to try the bra on and note how tight the cups are fitting. Measuring with a tape measure is not recommended as a useful measuring device
