Lucky Pine Cotton dress should be drycleaned by professionals. That is not to say that it cannot get wet.
The best way to smooth out the cotton fabric's wrinkles is to spray it with water and let dry while hanging.
The Outer fabric is 100 % cotton, the lining is 100 % polyester, and the embroidery thread is 100 % rayon.
The spray bottle is your friend in caring for clothing in general, that we highly recommend getting one.
