Freya Dress Outfit Freya Dress Retrofete Wholesale Black Freya Strappy Mini Dress Eyyo Wholesale Freya Dress. The Under Dress Freya is based on the cut of undergarments found in the excavations around Haithabu. Made of a sturdy, unkempt cotton fabric with a linen like structure, this women's undergarment is almost too good to be hidden under an overdress and can be worn just with a belt and accessories, especially in summer. The coarse structure of the fabric gives the dress an authentic look, and thanks to the material, it is still comfortable to wear on the skin. Classically worn as an undergarment, it enhances any garb and will not let you down, even on colder days.
