For sharing images of vintage magazine ads, fliers, promos, etc.
We're going to play it pretty loose with timeframe here so please don't get offended anyone :)
"Sizes 38-60" probably denotes waist or hip measurement
Modern sizing for ladies' dresses and pants (00 - 20s) is not a direct measurement
Still not sure what the units would be. 38 cm is tiny. 38 inches is larger than many.
