OptiMist is the new gold standard for busty clothing items, particularly after the improvement of their importing method.
While it's often a struggle to find appropriate fits on voluptuous models for most simmed VAM clothing, OptiMist's catalogue is designed to sim beautifully across buxom bosoms, and the textures/colors aren't bad too look at either. This Wide V-Neck Sweater in particular is a SUPER good look for the "casual-sexy, at-home MILF" look (I particularly recommend trying it out on a busty Helen Parr, as an improvement to her existing sweater option).
Keep in mind that Distance Scale (and possibly Stiffness) physics edits will be needed for slimmer/flatter models, but even here these resources do just fine.
