What is a likely reason that my sis has a vile odor after sweating? Is this common for girls?

IIRC, this all started years around her puberty time. Sometime after going outside, game over. Such a vile odor.

Entire fam agrees. Once, she was talking after coming home and father interrupted her and told her to bathe ASAP. Another time, she entered home and I felt it on 2nd floor jfc.

The big prob is she doesn't take bath daily and claims that deodorant doesn't work for her jfc.

IMO, no one else in fam has this prob.

While I remember another vile odor girl from HS, most girls seemed to always have some good perfume/ lotion scent. I am confused af guy lol
