I am trying out this linen blend skirt that I came across when looking for summery dresses so thought I would give my review in case others are interested--it comes in "denim" and white also.
I generally do better fit-wise in separates but of course for summery coolness and easy appearance, a dress often gives more of the right vibe and may be cooler as often not having a waistband. But then separates do allow changing up sleeves, fabrics, colors.
I am not a big "peace with the crease" person, which eliminates most linen from my wardrobe except for inexpensive linen shirts I wear for outdoor work and ignore the creases. But darker colors help disguise creasing a bit and blends tend to do better.
I am likely to keep this skirt as it has some HEWI properties--it sits at at my natural waist and fits without needing alterations, but not squeezingly tight; it has a side zip which give it a very nice fit through tummy and upper hip (no pockets thought!), but with the flare for hips, and it falls just below knee, which is "short" of a midi, but just right for casual wear, and has nice twirly movement. The good fit through the waist and upper part means I can tuck in or can wear shorter tops out, and a variety of footwear, all very casual at present. I don't currently have the perfect casual black flat espadrille or closed-toe sandal and am not actively looking, but that is a type of shoe I have worn well before and keep on my "list" if something turns up.
This is the type of fit one might also get with gores, or stitched-down upper pleats.
I considered the denim (I think in Tencel) as a good casual fabric/color but thought I would get more use out of black and the linen feel.
