What type of clothes should i wear...?

hey guys, i feel like this is a weird question, but i’ve been having a lot of self esteem issues lately. i know that when i get dressed up, and look nice, i usually fee good about myself, but lately i’ve been wondering what kind of clothes would look best on me...? i feel like my body shape is a little weird, and my stomach kind of sticks out a lot, as you can see in this picture...

(i added this picture of myself so you guys could get an idea of what my body looks like 😅😅)

i want to feel better about myself, and i want to start trying to look nice more often, but also feel comfortable. for the most part, i usually only wear a tshirt and jeans, and i hate wearing regular bras their so uncomfortable , so i always wear a sports bra 🤣

does anyone have any ideas of clothes that i could wear to make myself feel better? where i could buy them, or they type of clothes that’ll fit best?
