Being smaller in comparison to other TS4 previews… doesn’t make them not big.
Is this the video of the first gameplay you meant? With Sophia in the green top? The Sim they had in CAS did seem to have smaller breasts but I’d say that Sophia’s herself were larger than average, especially proportional to her body. I don’t really care if there is a ‘backstory’ to a Sim having large breasts or not unsurprisingly there are like a hundred stereotypes of the types of women who are “meant to have” big boobs, so you could use that to justify an entire town of DDs. Yeah, after I posted that I scrolled down and there was a picture of Holly, and she does seem to be the Sim with the smallest boobs in TS4 so far.
