It's impossible to tell, but this dress is made from very fine wale corduroy. the neckline is very flattering for a smaller chested woman, with a sharp cut (that makes a strapless bra required for peace of mind). the dress does have snaps to hold your bra straps in, but i went ahead with a strapless. the back has a neat square cut. the skirt is slightly longer, on both sides, which gives the dress movement, even though the material is heavier than typically used for this season or cut. i wore it
