Need help with tips on how to dress

After having my daughter I gained a lot of weight . For reference I’m 4’10 and I’m at 157 . I am very overweight for my height. I also struggle with pcos . This is my go to outfits for everyday . I don’t feel pretty at all and I can’t seem to find my dressing style because I have a belly apron as well . I’m just feeling really low about myself and any advice would be helpful ! Thank you ( I have started working out been at it for 3 weeks now)
