What Could Cause Armpit Fat? 8 Possible Triggers (List)

Ill-fitting Bra

The size of the bra a woman wears can be a cause of armpit fat. If the bra cups are too small for the breasts, the breast tissue could migrate or escape to the underarm region. The underarm bulge could also occur if the bra band does not fit the body properly. According to research, around 80 percent of women do not wear bras that fit. On the other hand, even if women can buy bras that fit their size, they can have armpit bulges still because most bras sold commercially are not designed to cure or prevent the issue. 

Further, women can make armpit fat less apparent by knowing how to wear a bra correctly. According to experts, the woman should fasten the back band first. Then they should place the breasts inside the cups before slipping the straps over the shoulders. Next, they should scoop the breast tissue under the armpits and place them inside the cups, arranging the bra cups to ensure that the breasts and extra breast tissues rest comfortably. Finally, ensure that the straps are not too tight. They can get the proper tension by slipping two fingers under the strap and adjusting the slide.
