my hip replacement was in Sept 2020. i did not invest in new clothes except for i got a couple maternity tops from Walmart. they are longer than regular tops and loose. i'm 5'3 and wore these along with very very loose old cut-off summer PJ bottoms.
you can't have clothes that are snug with which you have to struggle with on and off! i had to have help dressing for the first few weeks! i had to wear compression stockings for 4 weeks. that was bad enough and DH had to put them on for me. (and remove)
just think LOOSE and comfortable clothes!
