There is no strict dress code. You just should wear a tie.

"～たらいい": recommendation. You should have done it.

Your T-shirt and jeans are too casual. The least you could do is to ware a
tie.

"～たほうがいい" : reccomendation. You should do it.

There is no doress code cleary expressed, but probably you should wear a tie.

All are colloquial expression.
