well, an underwire doesn't really "cut it" for me either, but it works a heck of a lot better than sports bras! I still bounce like crazy, but tbh I've yet to find any bra that keeps you from bouncing like crazy when you're past a DD/F. It's just varying degrees of bouncy, lol. It's also possible they make underwire bras differently for a C vs. a DDD+, since my G/H/I/J bras look and wear a lot different than the underwire bras I wore as a younger teenager.
