Natural Hourglass & weight loss

I’m an hourglass. I gain 30 pounds in my late teens and I want to lose it now— my waist is still significantly smaller than my bust & butt.

Do yall think losing 30 will make be a smaller cup size? (I’m hoping so lol) Fellow hourglasses, what did your weight loss pattern look like?

I’m 5”2 & 156lbs.
