Here is my recommendation for how to dress for a successful job interview - obviously if you dont conduct yourself appropriately you're not getting the job, but at least you can look good while getting rejected.
Wear a single breasted suit - it has always been regarded as a bit more formal than the double breasted suit.
3 piece for the win - you mean business and strictly business, you like to maintain appearances and you look more organized - of course if you're smack in the middle of summer in 38 Degree (celsius) weather then wearing a vest might make you sweat a lot. so opt out in that case.
A notched lapel is the safest choice especially in formal business settings - going for a peak lapel is bold and some might see it as old school or even only appropriate for specific body types.
Red is a color that creates a lot of emotion - a sign of strength, and well, love, but lets leave that for valentine's day.
Double button blazer are an industry standard now, 3 button suits are a bit more old school and one button suits although look good, but I personally feel should be saved for fancier or less professional settings.
I don't know why but glasses give off some sign of intelligence, you could have no idea what you're talking about but "fake it till you make it"
Saving the best tip for last. Make sure everything is fitted appropriately. Looking sloppy will give off a bad impression. Make sure the pants are snug and tapered and cropped a tiny bit (no crease at the bottom), shoulders fitted, arms not too loose, and the jacket fitted enough to give you that semi-hourglass shape so to speak.
Hope you found this helpful. If you did, do me a personal favour and share this with anyone of your friends, family, aunties, neighbours, anyone who has any important job interviews or formal work events coming up. They need to see this.
