My bridesmaids and I all had posies of oriental lilies - mine was bigger and had more flowers, where their's was smaller and had more greenery than mine.

Sorry to be a downer, but tulips aren't in season in summer. You could try ordering them in special, but they will wilt very quickly - possibly won't even make it until your photos - I originally wanted to have tulips myself, but for a February wedding, it just wasn't possible.

Try Googleing flower's in season, and you should be able to find something that you like that is in season.

Good luck for your wedding!
