An air dryer might cause about 0.3 bar pressure drop in your compressed air system. Basically this means that you have to run your compressor at a higher pressure. This of course will result in more energy consumption by your compressor.
Dressing for a gala event is rather simple. It is typically a formal wear occasion. For men, that equates to a tuxedo or at the very least a suit and tie. For women, formal wear is typically a long gown with high heels, matching accessories and jewelry.
2. Wear the right suit. You still have to wear a suit to a semi-formal event -- just remember to avoid the tuxedo. For daytime events, wear a light suit that is usually cream or tan, a stroller or a director's coat, or a jacket in black or dark gray wool. For nighttime events, wear a dark charcoal or a midnight blue suit.
