Figured it might be worth mentioning that suspenders currently have inconsistent behaviour between Jean and Laura. When they have tops on, the option to shift the suspenders (toggling between covering the nipple or pulled to the sides of the breasts) work for both girls. However, if they are not wearing any top, shifting the suspenders works as normal for Jean, but both for Laura both positions are the version where it covers the nipple (note that it does still remember which position it's in for if you have her put on a top under them). The only way to have Laura shift them to the side while she's not wearing a top is to have her pull her top up, at which point she'll shift them to the side (though with the usual limits for that, where it is reverted to normal positioning when not doing sex actions).
Though my understanding is that you don't get the option to have the girls move their tops out of the way if they only have suspenders up there, it is possible to accomplish via console commands ( LauraX.Uptop = 1 , if not participating in sex options, girls will generally revert this and the other similar variables, Upskity & PantiesDown, to 0 quickly).
