Boo. I didn't find any Cleo's. This is all I found worth noting (c&p from my updated OP):

• Freya
• Honey in "Firecracker" - 36E, 32FF, 32GG, 34FF, 32FF
• Taylor (greenish) - 32E
• Ivy Longline - 32E, 32F (x2), 34F, 36FF

• Carys Longline - 34E

• Elomi

• Betty in "Navy" - 36G

• Caitlyn, I think - 38JJ, 40H

• Wacoal (I don't know anything about Wacoal's styles, apologies)

• 36G

• 34H

• Le Mystere (again, I don't know much about their styles, but every Le Mys bra I found was a moulded cup)

• 38D

• 36F

• 38F

And I would appreciate that! I can't do longlines or half-cups since they're much too wide and shallow for me, but I love balcony's.
