Breast change after second pregnancy

Hello. I’m a second time new mom to a gorgeous 5 month boy. I breast fed him for 3 months until I just couldn’t anymore. I’m very self conscious about how my breasts look now; kinda look deflated. They’re no longer perky like they were pre baby. I feel like I’m complaining about something so silly and superficial especially because I know child birth puts quite a toll on the human body. But am I the only whos felt this way towards their body? Does it get better?
