Really? You have never seen a thread about Saga? You have never seen how crazy people go when the word "Saga" is mentioned? I guess the real question is: Have you ever been on Newschoolers? Because it doesn't seem like it when you get on here and ask a question like this. All you have to do is type "Saga" into the searchbar and you will get upwards of 500 threads about their clothing.
And it isn't an investment. A better question would be, "Is it worth the money?"
No one can answer that but you because we don't know what kind of financial situation you are in. Suits can certainly be had for cheaper if you are strapped for cash, but if you aren't then it probably is worth the money. My Saga suit is amazing. The quality is top notch. I really don't know what else I could ask for.
Remember that teacher in high school that said "There are no stupid questions"?
He was lying to make you feel better.
