Hurtful comments on Dressing

Hi guys

I'm a 22 year old who likes dressing up fairly well, not over the top but neat and presentable. My mum hurt my feelings by telling me I dress like an old woman. So she got me some clothes. I picked some and left out some like pencil skirts. Reason is, I'm a pear shaped and very endowed, it makes me feel uncomfortable when I walk in public and get so many stares. I usually feel objectified. So most of my clothes I either reach out for skater skirts or Jean's and cute tops that will not reveal too much. Now I'm so hurt by my mum's comments and telling me I will not get far in life by dressing up like that. She wants me to show of my figure and look "hot". This is not me and I'm not interested to look "hot", just neat and presentable. Is dressing up a big deal because I feel like if it's not the clothes, she will tell me I have added weight, or my skin looks bad. Just something that pertains physical beauty and not teaching on inner self. Please help I feel so worthless.
