For what it's worth, to those interested, the National Council of Catholic Women in America passed the following resolution on athletic dress for women in 1928, which received the approbation of Cardinal Sbarretti and Pius XI for promoting the cause of Catholic modesty among women:
WHEREAS careful study of costumes made by the best sports-goods houses and used by the majority of private and public schools and colleges, leads to the conclusion that the necessary requirements for an appropriate costume for the girl and young woman in athletics may be met by the knicker-bloomer of material suited to the season; middie [sic] Blouses for children; tailored shirts with long (or short) sleeves for older girls; sweaters, sleeveless or with sleeves according to season; long stockings and "sneakers;"
BE IT RESOLVED that the National Council of Catholic Women recommend the above costume as best suited to feminine dignity and the best interest of sportsmanship and good health.
BE IT RESOLVED that the Council condemn "trunks" and other such objectionable extremes of costume which are as inappropriate and undesirable for women as are the particular forms of athletics with which they are especially associated.
The following blog post shows pictures from the decade that show you what that dress would have looked like:

John McNicholas of Cincinnati said to the above group: "The lives of our Catholic women must be a manifest challenge to the women of the whole world..." Of course, manifest means visible and obvious. Maybe this issue isn't one to write in all caps about, but it's certainly a sign.
