Carhartt Denim Overalls X-Small Short

These smell very strongly of mothballs and cheap perfume. Ive washed these 5 times...Regular detergent, still smelled. Vinegar, still smelled. Baking soda, still smelled. Borax, still smelled. Oxyclean, still smelled. Also fully sun dried them after each wash. They still reek and its so strong I cannot wear them. Its a shame bc they seem quality and fit nicer than other brands Ive tried. I know some clothes are treated with formaldehyde for storage but this is awful. This is the second pair of Carharrt denim Ive purchased from Amazon that had this odor. Anyway, Im 5'9" 151 lbs hourglass with long torso small waist with ample booty and M Tall gapped at waist but overall fit was good. Fit was not tight. Id post pictures but I cant bear to put them on again...
