I believe you are correct...but I remember my mother telling me as a young girl to feel the fabric...both sewing fabric and clothing. She had certain things she checked...never the brand or the store name.
Not a clothing story, but once she bought a lamp at Woolworths or some 5 & Dime store and made me promise to not tell anyone, because she was embarrassed. I remember people complimenting her on that lamp over the years!
