Female Fashion Advice

For myself, I am obsessed with cape dresses over the past few months. Unfortunately, i have no idea where I would often wear a cape dress and it would date itself quickly.

Day to day, I love the look of blazers with shorts and button down tops, but I don't feel like either suit me because I look much wider/bigger than I actually am. I prefer and feel more comfortable in outfits where my waist is emphasized and which are more form fitting.
