I've been wearing sport tops while commuting for about 2 years. I'm a smaller size and the tops are not very tight but it appears after wearing the top for about 4 hours the red area of each breast appears slightly white and shrivelled. Yuck. They recover OK after wearing a regular bra.
When I looked this up on the web, there were several articles saying that those lympth nodes need good circulation to carry away toxins (that cause breast cancer)
Can anyone recommed a top that supports but does not block circulation?
