With regards to the whole sizing up thing, I do have to stick up for her with some of the things she’s said it about! I bought that PLT crop bra thing that she couldn’t get over her head and lo and behold I couldn’t get it over my head either! I ordered in a 22 (normally 18-20, honestly!) it was awful, I even ordered another top at the same time in a 20 and that’s huge on me, so she is right about some stuff. The PLT joggers she’s wearing that are like leggings, I ordered them in a 22 (all my jeans and fitted bottoms are a 22) and they were the same, except I sent them back instead of squeezing myself into them I do find brands like that can be so off with sizing sometimes, but I don’t think you should have to siz up on absolutely everything like she seems to do
