Uneven boobs

So my 14 month old is slowly starting to wean . I didn’t change anything but at around 10 months one of my boobs just stopped producing as much and shrunk to nothing. I continued swapping sides at each feeding until I realized it just wasn’t filling back up. Still has milk if I squeeze it but not full. So now she’s just nursing on one side. Is there anything I can do to even things out? Hoping to wean soon so not wanting to creat oversupply. But My boobs literally look like they belong on two different bodies and it’s starting to be noticeable through my clothes! Driving me crazy
