These two photos came from the same batch from an estate in Chattanooga, TN.  Judging by these and the others in the lot, the date is early to mid 1920s.  Unfortunately, none of the photos were identified, but it must have been an extended family.

Side note:  I hope YOU are labeling all the photos you are taking - both digitally and on prints.  You need to do this.  Trust me.

The early 20s still required that women wear quite a bit of clothing for swimming.  Of course, things had gotten considerably smaller and lighter than just a few years before, but women swimmers in 1922 were still quite modestly dressed. 

It began with the cap.  Swim caps of this era were often made of silk and were lined in rubber.  That appears to be the case with our five females in the top photo. 

The girl below is more covered up that most girls on the street today.  She has on a swim dress with sleeves, and there are most like bloomers beneath.  She's also wearing stockings, and some cute shoes with pompoms on the toes.

I can't help but wonder if women wearing that much clothing had the same kind of swimsuit anxiety we suffer from today...

 

I have a special swimcap called a TURBONA. White oil cloth with long streamers. Instructions/tag still attached says something like cross the straps in the back and bring to your forehead. Tie a bow at the forehead. Price marked is 75 cents.
