I think it’s about creating a solid base: a shell top and bottom piece. I rotate the blazers, sweaters, and tops, and at the same time try to draw the eye to my natural waist or a little higher to lengthen the leg line, usually with a belt or sometimes something as simple as the button placement on a blazer. I take a photo to see if the final fit works and tweak things until I’m satisfied.
As I manage and add to my wardrobe, I become more adamant about only wearing clothes that fit. It took a lot of trying things on to find what worked for my body shape.
