It’s just a handy place to put my phone down for a second. Or stash a pen or a credit card.
My wife and I have a theory that the patriarchy removed useful pockets so women need to buy an external pocket in the form of purses.
That doesn’t require the patriarchy, just the fashion industry in general trying to sell as much as possible. Adding an entirely different and otherwise unnecessary article of clothing is a brilliant idea honestly.
PLEASE don’t put your phone in your bra. It’s odd, I found articles talking about no increased chance, but also remembered hearing about it in the news years ago, and saw these:
https://pmc.ncbi.nlm.nih.gov/articles/PMC7605549/ “Excessive smartphone use significantly increased the risk of breast cancer, particularly for participants with smartphone addiction, a close distance between the breasts and smartphone, and the habit of smartphone use before bedtime.”
https://pmc.ncbi.nlm.nih.gov/articles/PMC3789302/ “All [4] patients regularly carried their smartphones directly against their breasts in their brassieres for up to 10 hours a day, for several years, and developed tumors in areas of their breasts immediately underlying the phones.”
