The best material for trousers is white flannel or cloth manufactured for the purpose; I like cloth the best, and nearly always have my trousers made of it, as it does not shrink so much in washing, and that is a very important consideration if you play right through the season, from May to September. Braces are not worn when playing cricket, so there is no need to have buttons for them on your trousers; a strap and buckle at the back should be used instead. The straps should be made so that the buckle can be removed when washing is necessary, as the buckle is very likely to stain and cut the trousers if left on. Do not forget loops at the side for scarf or belt to go through. Many of the old cricketers used to wear belts to keep their trousers from slipping down; I prefer a scarf, as it looks better and will grip quite as firmly, and you will not run the risk of being given out caught at the wickets through the handle of the bat coming in contact with the buckle of the belt and the noise being mistaken by the umpire for a snick off the bat. I once saw a man given out for this very thing. It certainly was very hard lines; the ball passed so close to the bat that the umpire, hearing a snick, thought the ball must have touched it, and, on being appealed to, gave the batsman out.
Nothing can look much worse in the cricket field than to see fieldsmen with their hands in their pockets, and it is certainly not conducive to quick, smart fielding. I have observed that nearly all good fielders keep their hands hanging loosely by their sides, and are ready to dash after the ball immediately it is hit anywhere in their direction. Be sure to try on every new pair of trousers when sent home from the tailor's, or you may find out when too late to rectify the mistake that they are either too small or too large, and are completely useless. A revelation of this kind when you arrive on the cricket field and are getting ready to go in is destructive alike to high scoring and sweetness of temper.
Caps I think indispensable and preferable to any kind of hats, unless in very hot weather under a broiling sun, when some protection to the neck and back of the head is necessary.
