Definitely runs big. Usually a medium for sports bras top size 8/10 and I purchased a small.

Omg all that wishing and review writing of no more annoying removable cups in bras and I think this is the continued start of the future of all Lululemon bras! Love this bra- soft and perfect fit. Did I mention the best part is throwing it in the wash without having to put cups in or out! Now every single bra like this from now on please! The airy open back is also perfect! I’m a 32B with a muscular build and small fit like a glove.

I normally wear a 6 or small/medium in Lulu sports bras. I’m also nursing right now so I purchased this in a medium because my boobs are probably a size D at the moment. I cannot believe how big this bra was! The band and front were huge on me, to the point that I don’t even know if a small would have fit. The thin strap in the back may have caused it to fit looser than other bras. I was so excited to wear this but unfortunately had to return due to how large of ran. For reference I’m 5’4”, 130.

The band runs extremely big - even when you size down. This causes the bra to ride up all day long. I wanted to love this because of the style and the built-in cups, but it’s been designed very awkwardly.
