Today, you need to keep your bold ties and wear the new ones. It's called the narrow ties. Loose long sleeves and straight cut pants, as what we call them is no longer in. For women, they call it skinny; for men, it's called slim fit. Spread collars are still fine. Flat toe shoes are now dead. Either a pointed or a semi pointed shoes would be ok.
If you don't practice wearing the standard attire, it will also show that you have a low business standard. Remember, first impression counts a lot.
