There is always a colour we purchase season after season without knowing we have so much of it already. Mine is red!
I have good news for you. For this season and the next one, a monochromatic outfit will be your best bet! The more you complete your outfit with pieces of the same colour, the better.
Falling short on that teal handbag or those yellow shoes? I recommend to use a nude basic colour if you don’t have accessories so you won’t break the colour scheme of your outfit.
Put your pieces together on day light, many times we see colours on the same hue but when the sun light hits it becomes a different story.
You will probably have different hues (tones) of the same colour. As long as the outfit looks cohesive and you avoid to include warm colours if you are using cold colours and vice versa, you will get the look.
And finally, using colours instead of black or white will give you a more dramatic outfit.
This is how I did it, no shopping needed.
And always have fun. It is the most important when putting an outfit together!
