I ordered a 4 & 6 to wear to a Christmas party. Being middle age, I wanted something subtly sexy & fun. The size 4 fit perfectly. My bottom is very curvy and the dress hugged without being tight. Very comfortable. Because there isn't any structure to the front of this dress I chose to wear a backless bra which allowed the dress to hang better. The copper coloring & the surprise back made this dress a hit! The best part...I received compliments from my husband and my adult children!
