I sized up to a 6 on this one because I just had a baby. I LOVE the Dune skirts. Beautifully flowy and twirly. In terms of the Dune skirt's pleats: they actually hold up really well! Mine have been washed a few times each and I haven’t pressed anything yet. They don’t really wrinkle while you wear them either. The blue one which has the sheer chiffon-like overlay seems to have the more delicate pleats but they’ve survived a toddler and the washer so far! For reference i am 5’3​,​ 130lbs​,​ 34C; usually a S​/​size4​/​27 in denim.
