When it comes to khakis or chinos which is the correct term, there are a few different brands to choose from and one of the best ones is Dockers specifically their Alpha line. In terms of quality, style, and price, these are hard to beat.
Like most brands that make chino pants (khakis is actually the name of the brownish color many people associate these pants to), the Alpha line has a variety of different fits such as straight leg, slim, relaxed, tapered and so on. These days, it’s more fashionable to wear pants that are a bit tighter but if that’s too uncomfortable, then go with straight leg and avoid the baggy look.
Khakis/chinos are great for a more dressed up casual look. Many wear them with dress shoes or boots but you can wear them with sneakers as well. Alpha pants are fashionable, made with good quality material, and priced very reasonably. You can’t go wrong with them.
Some history on how khakis become popular.
Khaki was first worn in the Corps of Guides that was raised in December 1846 as the brain-child of Sir Henry Lawrence (1806–1857) Resident at Lahore, and Agent to the Governor-General for the North-West Frontier. Lawrence chose as its commandant Sir Harry Lumsden supported by William Stephen Raikes Hodson as Second-in-Command to begin the process of raising the Corps of Guides for frontier service from British Indian recruits at Peshawar, Punjab.
Initially the border troops were dressed in their native costume, which consisted of a smock and white pajama trousers made of a coarse home-spun cotton, and a cotton turban, supplemented by a leather or padded cotton jacket for cold weather. For the first year (1847) no attempt was made at uniformity. Subsequently, in 1848 Lumsden and Hodson decided to introduce a drab (khaki) uniform which Hodson commissioned his brother in England to send them – as recorded in Hodson’s book of published letters, Twelve Years of a Soldier’s Life in India.
It was only at a later date, when supplies of drab (khaki) material was unavailable, did they improvise by dying material locally with a dye prepared from the native mazari palm. Some believe the gray drab/khaki color it produced was used historically by Afghan tribals for camouflaging themselves. The mazari could not, however, dye leather jackets and an alternative was sought: Cloth was dyed in mulberry juice which gave a yellowish drab shade. Subsequently, all regiments, whether British or Indian, serving in the region had adopted khaki uniforms for active service and summer dress. The original khaki fabric was a closely twilled cloth of linen or cotton.
