Louie Vuitton monogram bags are probably the most classic luxury bags in the globe with the distinguishable pattern, the durable leather, simple styles plus the relatively cheaper prices. However, as versatile as the pattern is, it actually does not go with every outfit mostly due to the color pairing.
In my eyes, it goes best with fall/winter outfits as the classic monogram pattern is amplified by neutral darker colors like army green, brown and burgundy.
Not as good
In general, as the monogram is such a classic and highly recognizable pattern, more neutral colors work better so as to amplify the bag instead of more pop colors.
