I still fit in a lot of my old clothes and I was a 6/8 and had 350cc, the only problem I’m having is tight, structured tops in a 6, I definitely can’t do that anymore lol! & a lot of my dresses are now seriously booby whereas before they weren’t..
If you are between sizes you’ll probably have to go up to the bigger size but if you’re the same size in everything then I guess you’ll be alright in them still! If something is too tight now though so I doubt it will fit if you have big enough implants x
