Pattern Review – (Unknown brand) Vintage pattern 4902

Georgia picked up this vintage pattern in Vinnies recently. It has no date or brand on it, only that it was printed in the US. My guess is that it’s from the 30s or 40s. What do you think?

Georgia made the pattern up in Japanese 100% cotton Navy Hanataba. The dress was cut as per pattern, the only adjustments made were to shorten the sleeves to 3/4 length, eliminating the centre front fold and instead of a self belt to draw in the dress, Georgia added a self casing to just above the waist with self drawstring. Interestingly the original pattern came in half sizes?

One thing we do know about this pattern is that this 14 and a half is closer to today’s standard size 10 measurements!
