I would recommend this bra... I am 38D bought a 36 D and it surely smashes you where the twins do not hardly move.  I do not run... I do cardio so some jumping jacks and jump rope.. However, when I wash it... I put it in a mesh bag that I got at Walmart for $1 clasp my bra together and wash it in the bag.  I do NOT dry... hang dry and it's ready for the week!  Yes I wear it for the week and wash it on the weekends.  I can't afford another right now... so this wil due! The adjustable straps are wonderful as well.  It's tight to get in to so if you are looking for flattery? don't look here
