I really love Jumpsuits that have like the Palazzo pants thing going on because they are sooo flared they make my legs look extra long and my waist look tiny (when it blatantly isn't lol)
So if you're lucky enough to be able to pull off maxi dresses and Playsuits/Jumpsuits then I would say pack both, in fact you could probably even get away with literally just packing a few of each and just bring a tonne of accessories and cute shoes to make each look different. Oooooh that's an idea, I think I may do this and just bring a couple pairs of shorts. OMG in my head I've actually just packed my suitcase, Yessssss!!!!!
