                Pondy Bazaar, the main shopping area, stretches for around a kilometre on Thyagaraya Road. Pavement shops found in Pondy Bazaar sell a variety of items, including clothes, toys, and electronics, at cheap rates. Bigger stores often sell both indigenous goods and imported designer brands.

The area around Panagal Park is known for its silk saree shops. Many prominent jewellery stores are also found here. The variety in shopping options makes T.Nagar one of the most crowded areas in Chennai during the festival seasons (usually beginning in October before Deepavali and ending in January after Pongal). The area around Panagal Park has seen the oncoming of new clothing stores, including RMKV, Pothys, and Nalli, over the past few years.
