Hi! I’m similar to you, 5ft1 7/8stone petite frame, and I was going to get 250 and instead got 275ccs, some days I think they look big and some days I think they look small.
But at the end of the day I know 275 was the highest I could have gone, so if I did get 250 (which I was going to until the day) I know I’d never stop thinking, ahhh but what if I did get the 275s.
So I’d say go 270 so you don’t regret not going bigger when they settle. Plus it makes this recovery feel more worth it:’) (I’m 2 weeks post op btw) plus if I do redo in like 10 years can always size down then!
