Suit vs. Tux
A suit and a tux are different variations of the same thing. Let's take a look:
A suit (noun) includes garments, such as a jacket and trousers, which are ideal for work or less formal occasions, such as a dinner engagement.
A tux (noun) is a fancier style suit often used for semi-formal or black-tie events, such as weddings, award programs, royal affairs, etc.
