Tank It Up
Add a neutral coloured tank to pull the look together. These go together like mayo on a sandwich.
Wave Your Sneakers Goodbye
Add a pair of platforms or boots to keep the look chill and chic.
A blazer would transform the whole vibe of your track pants, just make sure that your blazer is tailored and monotone.
Shy away from anything ornate, may it be a watch or a bag. Everything should fall in line. This look is statement enough.
