Bring a large pot of salted water to a boil. Add the macaroni and cook according to package instructions until al dente, usually around 7 to 9 minutes. Drain and rinse under cold water. Set aside to cool.

In a large bowl, combine mayonnaise, vinegar, and mustard. Season with salt and pepper to taste. Whisk until smooth and creamy.

Once cooled, add the macaroni to the dressing along with celery, red onion, bell pepper, and pickles. Fold gently until coated.

Taste and adjust flavors with more salt, pepper, or vinegar as desired.

Cover the bowl with plastic wrap and refrigerate for at least 30 minutes.

Stir before serving and transfer to a serving platter. Garnish with freshly chopped herbs if desired.
