I swatched 15 minutes, blankety, hue, angel, myth, fleshpot & a couple others with c-thru & lightswitch lipglasses over...but IMO The best match was Aloof with Lightswitch over it (3d). Or any other pale sheer pink lipglass.
It looks like a very light pink undertone in the photo, not peach...at least to me. Think how much l/s, l/g they would sell if they just mentioned what she is wearing on her lips somewhere.
MAC needs to bring back Aloof as perm...it is an awesome perfect pink!
