“Someone should tell those guys that the baggy pants look is totally out of style.”
You're walking around your neighborhood with a friend. You notice a group of guys wearing big, baggy jeans. That used to be fashionable several years ago, but you don't think it's cool anymore. You make a comment about it to your friend.
Someone should tell those guys that the baggy pants look is totally out of style.
"Baggy" clothes are very loose, so that there is extra fabric hanging down in places. An example of baggy clothes is the jeans and shirts that hiphop musicians and fans wear.
"Guys" is a casual term for talking about men, especially young men. For example:
Those guys over there are looking at us.
You can describe a specific style of dress and appearance with the phrase "the ___ look". For example:
the lumberjack look
the punk rock look
the cowboy look
the preppy look
This phrase is not for describing a costume which someone wears once for fun or for a party; "the ___ look" is for talking about someone's chosen style of dressing.
When something is fashionable, English speakers say that it's "in style".
When something is unfashionable, English speakers say that it's "out of style".
And when something is very unfashionable, you can say that it's "totally out of style".
A funny point to note is that using the word "totally" in this way is a little bit out of style now. This word was really popular with young people, especially teenage girls, in the 1980s and '90s. You can still use "totally" as an adverb, but just try not to put it in every sentence!
