I ordered the Juno & the Maia bra from moving comfort, both in 34DD but the Juno didn't fit well as the back was a bit tight & uncomfortable.

The cup support in the Maia also seems better than the Juno, probably due to the underwire in the Maia.

though you cant notice that there is underwire while wearing it, the Maia gives the effect & support of wearing a bra & a sports bra at the same time, but the comfort of wearing just one. The Juno has just a foam lining for support....

so if you're going for the Juno, I'd suggest going a size up in the back (eg 34 to 36) but if you're a DD or more - I'd suggest going for the Maia!!
