“we follow the custom of the current behavior” may or may not be a good argument but the proof from the A”H does not have legs to stand on. He is discussing that since rm”l married woman go with their hair uncovered, we can make brachos in front uncover hair. He holds it is forbidden to walk around uncovered both there and in even haever. The sugiya of making brachos has nothing to do with walking around half naked. There is an iyan to get dressed underneath covers. That would be more comparable than making brachos.
As in a side, We can make brachos in front of other man because their bodies to us isn’t eruvah just like a woman to another woman.
All the best
