I've been looking for ways to keep up with this transitional weather. We are having an Indian Summer -as they say- and I'm loving it, but can't seem to be able to pull of the right outfit.
I'm either too hot or too cold.
I know that layering is one way to go about it.
But I'm wondering how to layer without looking like a mini version of hulk?
Because of my posture, any more fabric layed on my body will just make me look more bulky.
Or do you have the golden tip for me? Do share. For now all layered looks I see and like are not so suitable for my bodytype.

How do you practice the layer method?
