We had a discussion on the forum a few months ago about whether colours and colour combinations can look dated. For example, a particular combination was dated because it looked “very ’80s” to some forum members.
Of course, some colours and colour combinations are more on trend, fresher and “newer” than others because they are the so called colours of the season. But I do not think that colours and colour combinations have an expiry date. It is the silhouette of an item, or the items you pair it with, that makes it look dated. Much more so than the colour.
If certain colours and colour combinations are attractive to you, if you love their vibe, and if they look great against your complexion, then I say they are always in style.
