I purchased this bra in size 12. I am 5’9/175lbs/36C. In the IVL leggings I wear an 8. I sized way up for this bra just in case. This bra was so TINY! I actually laughed when I took it out of the package. It had absolutely no stretch. I could barely pull it over my shoulders and the band was suffocating. On top of that, there is no padding so my nips were fully visible. I had high hopes since I love the leggings so much, but I guess my (average) size is excluded from wearing this style :/ I will be returning.
