Unless, I wear my father's suit, oh yeah, that's an idea, I will do that.

Só se = Suggestion!
Unless we... = Suggestion! What if we did this?

I will give you an example of a dialogue with the expression ''Só se'':
- Vamos ao cinema?
- Estou sem grana.
- Só se a gente for na praia então.

I think the issue here is not English but Portuguese. You misinterpreted the original. ''Só se'' is an expression that means I wonder if, a suggestion to myself, I just had this idea, it just occurred to me, it does not mean I can only do this or I will only wear. You misinterpreted the original and was rude to me for no reason. I am not trying to teach you English but it would do you good to have some lessons in Portuguese and manners.

I wonder if you have seen an episode of How I Met your Mother where Barney uses a dozen of ''unless'' in a row at the beginning of the sentence to introduce future scenarios and possibilities. Unless, of course, you don't watch that type of show.

The kid said to himself: "I WILL only wear a suit if it's the suit my father wore at his wedding." (emphasis added)

If you want to use the word "unless," you would have to rewrite the phrase saying that the kid said to himself: "I will NOT wear a suit unless it's the one my father wore at his wedding." (emphasis added)
