Bisue ballerinas - sizing help?

[OhCobblers]

Have just bought a pair online and assumed my normal size would be ok. They're coming up a little smaller than I would have liked but they're soft suede so am hoping they'll stretch?? Can't exchange for the next size up so it's these or Return them!!
Does anyone have experience of their sizing and could advise?? they're beautiful and I don't want to send them back

I bought a pair in my normal size 7/40. They also have come up a tiny bit small. Next size up would be too big though I think.

I love them so will just cope

I am 5 or 5 1/2 . The 5 in Bisue fits. I love them

I've been walking around in them and my left foot is squeaking quite loudly in them!
Such a shame but think they need to go back.
There are a few in the brand alley clearance sale today at 80% off for anyone looking for more!
