I bought this dress along with the "Before The Fall Hoodie and Dress set" for casual summer wear, and I find this fabric to be thinner, but softer than the dress set. Because it is softer, it's more prone to bunching up and creating wrinkles though.
The quality is still very nice and more breezy/cooling for summer, it's just hard to hide bra/panty lines. Otherwise it's not see through at all and the quality is nice with no loose threads.
The armpit area is also high, could be tight on some people but offer coverage of the armpit fat which is flattering. The slit on the side is also great because I rarely find this dress to ride up while walking
It's definitely become a staple in my closet now :)
