Hi, I am writing a poem for my sisters wedding. I need to know if it is good english to put

with the biggest smile you've seen?

I know it should be You've ever seen, but that makes it too long.

I don't want it to sound wrong, what do you think ?

Thanks.

you can get away with stuff like that in poems.

Sounds fine - people will know what it means.

Thanks.
