I guess I am an "H" , just straight!

I am 5'3" and measures 34, 26.5, 35.
I love swimming and have a swimmer kind of body, my shoulders are even slightly wider than my hips. I can fit into a pair of size 2 skinny Jeans but my top is usually a size 4.
When I gain weight, my waist and my face show first, then my upper arms, my thighs seem to be the last.
I have short arms, and they look thick, my worst part, the next worst is my waistline, I just don't have the tiny waist partly because my narrow hips.
