>>2262479I'd like to add that Nene is a literal midget with an especially slender body on top though, which makes her size all the more impressive. Passionlip is likewise "only" 154cm tall.
Meanwhile Titty Morgane is an adult woman with the length to match, she'd be closer to Cattleya in height. I'd have included an upper body pic instead of just a bust shot for her to show this better but I couldn't find one.
The way I see it height, body build and thus proportional size is important. Girls can theoretically just fatten up to get themselves a bigger bust size, which is kind of cheating. Meanwhile being slender/small and having a similar bust is only possible through winning the genetic lottery.
Someone like Tearju would be in huge, but her body build/height overall puts her in large.
