Factory pleated ponte dress in stripe (SU14, A5221, $98) 71% cotton 29% spandex.
Size S vs M – I didn’t realize this was a ponte, so I tried on a M. It fit ok, but felt big. The S (on the right) definitely felt better. It feels like a casual dress. My flip flops felt just fine. You could also wear a cuter wedge or otherwise heel with it.
The dress isn’t lined and I didn’t find there to be an opacity issue. There are bra keeps in the shoulders.
I have recently realized I don’t like variegated stripes, but it works on this dress.
