How do I dress for my body type when I feel too chunky too be skinny but too skinny to be chunky?

At nearly 21 years old I’m embarrassed to admit that I still have no idea what kind of clothes look right on my body. Maybe because of body dysmorphia, or maybe because I just never learned.
I have been trying so hard to get healthy, but my body still looks the same, and it’s taking a toll on my mental health.
My counselor recommended that maybe I could try to find clothes that I feel cute in and that fit the more womanly body that I’ve developed during college (I used to be VERY skinny in high school, not that I knew it at the time, and when I gained weight in college I felt terrible because none of my old clothes fit).
Do any ladies have advice on how to dress for my body type? Or how to feel comfortable in my clothes? I’m especially self conscious about my belly, but I really want to feel good about myself again!
