Oestrogen can affect women this way. Such as when a woman goes through puberty oestrogen causes the growth of breasts and hips this is 'hormonal weight gain'. When on the pill some women find they do gain weight on the hips and thighs. When women carry this weight around their thighs and hips it's the natural hourglass figure. Women are meant to carry weight here.
you might notice that older women after they go through menopause their hormones change again and the weight is distributed differently again. Oestrogen acts to protect women from heart disease by distributing the weight on their hips and thighs and not on their belly, which is the most dangerous place to gain weight (men gain weight in this area). After a woman goes through menopause her thighs and hips don't carry as much fat, if you look at older women (who are not overweight) usually you will notice they have very slim legs and tiny hips but can have some weight around the mid-section.
