“我想送花,但认为这太古板“ 用英语怎么说

I want to give some flowers to her ,but i think it's too old-fashioned..
old-fashioned意思是老传统，太老套了，就是说太古板了。

I want to buy some flwers for her.But i think it's seem out of style.

out of style: 过时的

i want to buy some flowers for her, but i think it's too old-fashioned.

i want to buy some flowers for her, but i think it's too precise!
更好。precise 有拘泥的, 陈规的意思，也就是和古板差不多

I want to send flower,but I think it is something old-maidish.
