Vintage 1950s-60s L’aiglon union label dress 35/26

Pictures don’t do this dress justice! Vintage 50s-60s Deep blue and green plaid with yellow stripes L-‘aiglon union label dress. 4 dark buttons run down the front. Has hook and eye waist closure with snaps on the skirt to keep closed. Cotton shirtwaist dress with a slight sheen. Has been hand washed- no vintage smell. Measures at 36 chest ,pit to pit( meant to be more of a looser fit I believe) and a 26” waist. Belt loops -no belt. Beautiful condition; left open in pics, doesn’t fit my form
