I have larger boobs so this is a good fit for me!! The straps at the back are adjustable (to make it tighter if you want to do some higher intensity based sports/workouts) and the zip in front has a little hidden hook for extra security. The back of the zip also has extra lining, so the zip does not press onto your skin. The band at the bottom is wide and comfortable. I wear this for my HIIT workouts and they give me the support I need! I match it with my favourite polka sporty 7/8 but you could also totally wear it separately. It is also breastfeeding friendly for those wanting this as an option. I would highly recommend this!
