I’m glad I went by the size chart for under bust measurement. It seems that all Craft items run small but there is a warning to this. I have mixed feeling on this bra not having “modesty” coverage but it is super comfortable. I did have to remove the tags as they irritated the skin immediately- they were easy to remove though and you can’t even tell tags were ever there. I’m 34C and not sure about longer runs - I look for more support for those - but this is nice for less intense workouts.
