Got some breast forms in the other day, and they're, interesting. Despite the meme of "If I had boobs I'd just want to play around with them all day", I honestly feel complete indifference.
Regardless, I'm really liking how all of this padding and formers are coming together. There's a couple nagging issues, the butt padding is squeezing the hip pads in a unflattering way and there's nothing I can do about back fat at the moment, once I get a proper full body faja I think everything will finally be together to properly crossplay.
To the point of the post, I bought these forms (Onefeng kvs9 for reference), 840g as a pair (they honestly don't feel that heavy), which was listed at a size of "42C", which considering I was shooting for 38DD thought would be right on the money. I get them in, and they honestly seemed kinda small depth wise. The 7cm depth that's listed is a bit of a misnomer, the mould is probably 7cm deep, but because there's a really deep back the actual depth of the silicone is probably closer to 3 or 4.
Then I put them on, and they're the exact kind of volume and shape I was going for! (Some overhang would of been nice, though there's no real getting that with this form style, or possibly with this cup size. And there's an annoying lip of sorts around the edge of the actual silicone, which I'm hoping will get resolved whenever I get a thicker bra), but despite the intended "38DD", looking down with them on they look more like somewhere between Cs or Ds on the chart in the following post, and the implied size is readily apparent in the photos. Then I measure their size with them on, ~33-34in underbust as expected, 41in bust. Which is apparently a 38G!
