My daughter is Imogen and we love it 😀 she’s often Immy. She has a friend called Summer but they don’t shorten it so not sure on that one
I know a nickname for Summer which is ‘Essie’ - soo cute!!
My niece is Summer and we call her Sums, never planned to but just evolved. My SD is Imogen and we like Mim x
Imogen: Immy, Ims, Ginny at a push. Not sure how I’d nn Summer though!
Summer, with Sunny as a nickname!
