I am a petite, busty woman (32DD-DDD). In past seasons, I have paired the older design of the Coeur sports bras (circa 2017-2018) along with the tri-tops that have a built-in shelf bra. When I doubled those two up my girls were tightly packed enough to race comfortably. I ordered the Not Going Nowhere sports bra with the hope that I could pair it with one of my 1-piece Coeur tri-suits during a race or with a bike jersey during a brick run.
Now that you have some context, let me say that overall I really like the design of the Not Going Nowhere sports bra. The wide elastic paired comfortably with my HR monitor, and I always love the stash pocket. And, the fabric would continue to dry out well after a swim without chaffing. However, this bra is definitely not supportive enough for running, for me. I could keep it to use for cycling, but I plan to return it since I already have other Coeur bras I could use for that purpose.
I appreciate Coeur trying to design a bra for us bustier women, and Coeur will continue to be my go-to company for all things except running bras.
