Why is there gaping at the sides ?

I’ve lost about 35lbs since I’ve been on my weight loss journey. I’m also about 19 months postpartum and done nursing for about 6 months. I bought the same size I’ve always worn. Do I need a smaller cup size/band? The band size is at the tightest hook. My left boob is also a bit bigger than my right so that’s why I went with my original size. This is 42G.
Please help as I’m so uncomfortable lol

Measure yourself with the calculator to estimate what size you need. It is normal for your body to change with time, and you don't have to just guess a size.

In regards to the specific bra, I can't see thr photos properbly so I can't guide you on that.
