He did what he did with pretty much every character. Maybe this is how he thinks Sophia looks best. We all know how he constantly keeps working on Sophia's model. Personally it was never an issue.
They did look a little too big on Day 17 and 18 yes but Day 19 felt fine to me. I mean there lots of women in the real world with such breast sizes so it never pulled me out of the experience. I was like okay. This Is acceptable. Also a I thing I feel is even Sophia's model has gotten a lot bigger than it was initially. Like her body structure, so maybe he started making adjustments to every part and settled for what we see now.
Yes, I noticed her additional body morphing well over a year ago. Happily, (for now), he hasn't decided to give her an arse the size of British Columbia, as seen in some "Mom" characters.....think e.g. FotM, DoD etc. There are lots of women with such breast sizes in RL but they're not Sophia. It just doesn't look right for someone to increase in such an obvious way without plastic surgery, which we know she hasn't had from story dialogue.
What she does now is conform to the stereotype "MILF" favoured & expected, if not insisted upon, by a certain demographic & which is prevalent throughout the games found in F95, good, bad & indifferent. I play none of them because that's how fed up with the stereotype I am. It detracts from AWAM's appeal IMO. [If Sophia had looked this way at the start, I probably wouldn't have played this game]. So, the update includes the infamous romper, with the boob pockets, which act as a showcase for the jugs within. We'll soon see why L&P decided on this outfit, if indeed it has much significance but I'm hoping Sophia doesn't poke anybody in the eye. I'm also fervently hoping that she hasn't morphed yet again.
