Be careful to not wear pants that are too tight.  Only you can judge what too tight means, but you should be cautious.

Slim fit pants have a snug fit through the legs and end in a small leg opening that can be anywhere from 9" to 20" in circumference, depending on size.

When slim fit pants are made of denim, they can be called skinny jeans.  Other names for this style of pant includes drainpipes, stovepipes, tight pants, cigarette pants, pencil pants, skinny pants, gas pipes, and skinnies.

Can this type of pant be too slim?

Yes, you can potentially buy a pair of slim fit pants that you won't actually be able to fit into.  In some styles, zippers are needed at the bottom of the leg to facilitate pulling them over the feet.  Be sure to try them on to make sure they fit and can be worn.  Some slim fit pants are made with a percentage of spandex to allow for some stretch in the fabric.

Here is a little history on tight fitting pants.

Tight fitting trousers were fashionable from 1805 until 1850, being descended from the loose work trousers worn as a political statement by Sans-Culottes during the French Revolution. These "pantaloons," popularised by Regency era Englishmen like Beau Brummel, were worn high on the waist and tailored to accentuate the leg like the breeches previously fashionable among the upper class. Pantaloons were tied (or buttoned) around the ankle and commonly put into boots.

Drainpipe trousers re-emerged in the 1950s, with popular Western stars such as the singing cowboy Roy Rogers, The Lone Ranger, The Cisco Kid, Zorro and Gene Autry and actresses Marilyn Monroe and Sandra Dee wearing their pants very slim to the ankle from 1955 onwards. Tapered jeans became most notable with country music stars and with the birth of rock and roll in the 1950s, when Elvis Presley donned slim-fitting jeans and shocked the country.

In the early 1960s, drainpipes were worn by numerous rock bands and musicians, including The Beatles, The Rolling Stones and Bob Dylan. Fashion icon Audrey Hepburn also raised the popularity of drainpipe jeans. Slim fitting pants and jeans were worn not just by members of the teenage Mod or greaser subculture but also ordinary people. By 1962, Sears was selling tight jeans made from "stretch" denim that incorporated elastane.  The trend lasted until the end of the 1960s when "hippie" culture gave rise to flared pants and bell bottom jeans.

In the early 1970s, glam rock and rockabilly bands reviving the Teddy Boy look popularised drainpipe jeans in contrast to the flared trousers worn by hippies. Red tartan drainpipe jeans (as they were then called) were popular in the punk subculture of the late 1970s, and were worn by many bands and scene leaders such as Ramones, The Clash and Sex Pistols.

Skin-tight acid-washed jeans were also popular in the 1980s with most heavy metal bands, and in particular those in the thrash metal scene, such as Anthrax, Megadeth, Metallica and Slayer. This was the trend for those who did not wear spandex, which was popular with the dominant heavy metal scene at the time. They were often worn with white high-top sneakers or basketball shoes like Converse. By the late 1980s, drainpipe pants were largely superseded by straight leg jeans like Levi 501s, but remained popular among fans of hard rock until the 1990s. Tight fitting jeans were also worn by pop stars like Michael Jackson and Freddie Mercury.

By the early 1990s, many glam metal bands such as Poison, Mötley Crüe, Kiss, Bon Jovi, and Slaughter, abandoned spandex and wore form fitted jeans. Tight jeans were also worn by members of the casual subculture from the late 80s until the mid 90s, including Ewan McGregor in Trainspotting. With the rise of grunge and hip-hop music in the mid 1990s and the post thrash movement, drainpipe jeans quickly went out of fashion.

The 2000s saw the continued rejection of slim-fitting pants and jeans throughout the early and middle years in mainstream fashion. However, in 2005, fitted pants were reintroduced to the mainstream market for women. This new style of pants was called "skinny jeans". Skinny jeans first spread to men's fashion in 2008.
