Hi Nepter
Any "evolution" study requires dates to be accurate.
In some of your images the dates are in the background and obvious. But with one or two exceptions (eg #3 below), my Yandex reverse image searches have not found any dates written on the images you have posted.
So where do these other dates come from?
Were they already on the images?
Did you add them as a result of your research? (eg report in a nudist/naturist magazine of the pageant)
or guesswork?

#1 "France 1910" - reverse image search suggests 1950s not 1910. It looks like a burlesque studio shoot rather than a beauty pageant - I've never seen women dressed like this for a pageant.
#3 "1945" looks like pin-up/porn rather than a beauty pageant to me - I've never heard of a topless/underwear pageant. xhamster.com/photos/gallery/pin-and-vin-1-pin-ups-vintage-pre-1963-8461080 has the 1945 date
#4 "12.4.1952" an exact date! has a watermark saying "A smokin' fake". Reverse image search says fake Judy Carne or fake Judy Garland (without any date)

#5 "june 62" doesn't look like a pageant just a general naturist scene
The following look like 1960s/70s hairstyles to me:
#7 "1953"

#1 "Nude Contest 1946"
#6 "1947"

#7 is not a pageant but from a set called "The Joy of Pantyhose" xfapix.com/49559-gina-gerson-kiki-b-silvie-luca-michelle-doris-ivy-russian-porn-gallery-3532685.html
I'd love to know where you got the dates from as I am fascinated by this subject.
Thanks
