Obviously this is a really touchy subject but I think he was just talking about her boob job, which she didn't need to look great btw, which lead him to say "lighter". But honestly, if she already cares so much about what Dave's opinion on her is, him saying that her promos and in-ring abilities are shit right before that should probably be the more important thing for her to focus on instead of him not liking her new boobs lol
Once again, and I think I said this a couple times now, it's people making a big deal out of this dude's opinion. There's a thing called unpopular opinions and Dave apparently has one on Peyton's physique/chest size in a very looks-oriented business. Stop holding his ratings and thoughts to such a high regard as if he's wrestling's only voice of reason. That's all you should take from this whole thing.. Dave's just a mark, not the chairman or anyone else in charge for that matter
