Defective and see through.
Size: Medium, Color: White
For such an expensive linen dress, it should have no issues. It's see through on top and had snags in the bodice front. Also one of the stitchings over a breast seamed a little crooked. Zipper is OKAY. Does have pockets. Is a sturdy feeling breathable material but even covers would show through. I'm 5'9" and the Bodice part came low enough for me which is really rare and was very flattering. I got a medium for bust room so it was just a smidge loose in the waist but not bad enough that I wouldn't have kept it if it didn't have big snags in front. For being $90 it should absolutely not be see through.

Buy it!!
Size: Large, Color: Red Rose Floral
Love this dress! the fit is amazing and the fabric is linen but feels soft. It is lined, not see through at all and the straps are thick enough for a regular bra. It's a bit expensive for me but I was obsessed with the rose print, just love it.

Nice but TOO SMALL
Size: Medium, Color: Whisper White/Black Polka Dot
This dress is cut so small. I usually wear a medium and it didn’t attempt to zip up. If you buy this order a size or TWO up so you can actually fit it. Other than the size issue the quality is nice. The black polka dot print is cute.
