Answer: Cup Sizes (Patreon)

As you can see,  Bonbon has the most average looking boobs of the trio.
Pudding and Parfait have measures too big for the standart brassier manufacturers.
I had to use Theoretical measures based on the charts of the US cup size measure thingy.
Which as a result , would leave Pudding with a 42N cup size and Parfait's gigantic 40T size.

I hope this answer satisfy you people, because i had to go the extra mile and calculate by myself the approximate measure of the boobs of the girls for this one ;_;
