Inverted triangle body shape?

So I think I am just starting to figure out what my body shape is. Shoulders broader than the hips, less waist definition, I do think I fit the inverted triangle body shape more than anything.

My main interest when it comes to dressing up is pastel/lolita/cutecore fashion, and It does work in theory? With the whole idea being that I need to add more volume to the lower half, and have mostly fitted clothes for the upper half, without putting too much emphasis on the shoulders. But has anyone actually tried this?
