Training bras often provide minimal or no support, and may serve aesthetic purposes to fulfill cultural norms and local beauty standards.
[10] Prior to the 1950s, girls in Western countries typically wore undershirts until their breasts were large enough to fit an adult bra.
[13][14] The emphasis on the female figure came from several sources: girls wanted bras at an earlier age than ever before, while their mothers felt they should help their daughters develop a "good" figure; doctors who valued maternity over all other female roles; and companies who saw a profit in persuading girls and their parents that adolescent breasts needed support.

[9] In magazines like Seventeen and Compact, adolescent girls were encouraged to purchase undergarments like "Bobbie" bras, Formfit girdles, and "Adagio" by Maidenform that were "teen-proportioned".

[20] The design of some training bras do not provide actual support of any kind, and may serve aesthetic purposes to fulfill cultural norms and local beauty standards.
[3] Some girls are embarrassed about wearing a bra and resist parental pressure to take this step, turning the event into a potentially traumatic experience.
Because bras are mass-produced to fit industry standards, a young girl may not understand that an ill-fitting bra is not her fault and may blame herself, thinking something is wrong with her body.
[9] Still, others recognize developing tissue in breasts as sensitive and, at times, needing cover to maintain comfort, even if only psychological, for the wearer.
