In an ideal world, these fellas are right: never buy a suit online. That being said, I've worked in legal aid where I'm supposed to look good but make less than $50k a year. I think the best way to go is try on at store and then buy online. You can then get it tailored. Be picky and don't be afraid to send things back. Just because it is a huge discount, doesn't make it a good deal. My favorite suit is from Yoox. Fits very good and was 80% off.
