Help me where to start?

At the time of my wedding I was really thin, then we were out of india for 3 years, so no saree. When me moved to India I put in weight. So I restitched some of my blouses since i couldn't alter so much. Then i was pregnant again my size started to change, i don't want to stitch the blouse, so bought a golden colour blouse and used it for all pattu saree. I know what you think, it was not that bad. After the delivery, again changes. I am going mad where to start, when i will wear good matching blouses :bowdown
Stitched some blouses last month, when tested those were fitting exactly. Now it very loose. No good fit.
Help me where to start again
