A little thin but very cozy and comfortable, soft fabric
Size: Large, Color: Navy
Thin but super soft and extremely comfortable. I would have liked the fabric to be a tad bit thicker, thus the four stars instead of 5. I wore this with a denim blazer. It is a beautiful navy. I think I will order a size larger than normal and maybe then the thinner fabric won't be such an issue. Nice sleeve length, not too clingy.

Fit Comfort and no high slits which spoil long dresses
Size: X-Large, Color: Dark Green
Why such high slits? Why 2 splits? Always have to sew them up for more coverage and modesty, especially when seated. The manufacturer/seller could appeal to more, and all ages of customers considering this dress purchase, if not for these too long slits either side.
