Its defiantly possible hun. I was a 32c/ 34a I now wear a 32gg/34f! I’m the same height as you, and around 10st. At the end of the day, as long as you are doing it for yourself and you think it’ll make you feel better and your life better, go for it. It’s normal to be nervous, but you’ll be fine. Everyone at MYA are lovely 🙂 xx
