First things first, according to you, do you think you are overweight?
If you feel comfortable with your body size and weight, then your dear husband will have to get used to it and love you like that.
However, if you also think you are overweight, and you don't feel comfortable in your current state, then it will be important to lose some weight as this will make your husband love you even more.
When your husband asks you to put on leggings, maybe he is not satisfied with your body size and would rather see it covered.
I think you should ask yourself what you want first before thinking about your husband.
If you want to please your husband, go ahead and ask him if he will be pleased to have you cut of your extra weight.
Otherwise, I would rather advise you to stay as you are, but first what do you think about yourself?
