I can understand why you love
Lily it's a somehow a irresistible name but a lot of other people seem to think the same ;)
Imo
Lily it's cool, innocent and elegant all at the same time and thats why i also love this name. But i wouldnt use it anymore, there are simply to much Lilys out there.
But there is still the posibility to use the name
Lilian,
Lillian or
Liliana and
Lily as a NN.
