Button up’s

How long did you have to wear shirts with buttons post op? I’m getting DI in a couple of weeks and I’m having a hard time finding shirts that are button ups and that I’m fine with the texture. I like stretchy material not material that makes me feel like I can’t move, and most of the button ups I already have or can find are cotton and I just feel like it’s too tight 😭 I’m really looking forward to wearing my normal tee shirts post op and seeing how they’ll fit on me but I’m not great with the cotton texture of button ups
