thick and thin
All circumstances together
Through thick and thin means through all circumstances, whether favorable or difficult.
The phrase almost always follows "through" and suggests unwavering loyalty or persistence: She stuck with him through thick and thin.
The thick and thin refer to obstacles—dense forest versus open ground, or perhaps difficult versus easy going.
