It just seems like an odd fit for Sims 4.
H&M and IKEA stuff were broad enough that they fit in with the clothing and furniture already in-game. Moschino parodies pop-culture, which I don't think would translate in a game, and could just end up looking like bad CC. It seems like such a bizarre match-up, what sims players would want with a niche designer, I don't know. So it depends on the clothes, really.
That said, I'm really looking forward to the other two packs this is sandwiched between, and the fashion photography career seems interesting, so I can't be annoyed. I'm mostly just enjoying myself watching the bewilderment of everyone, and the complete silence when they announced the stuff pack at EA play.
