In Grand Theft Auto 5, after assisting with the Jay Norris assassination, players must don a smart outfit before proceeding with Lester's next mission – a jewelry store reconnaissance. This guide explains how to acquire suitable attire.

Accessing Michael's Wardrobe:

To quickly obtain a smart outfit, head to Michael's house (marked as a white house icon on the map). Ascend the stairs to the second floor, enter the bedroom, and access the closet. Select the clothing change option (top-left corner of the screen). Choose the "Suits" category (second from the top) and select a full suit; the Slate, Gray, or Topaz suits are guaranteed to work.

Alternative: High-End Clothing Stores (Ponsonbys):

Alternatively, players can purchase suits from Ponsonbys high-end clothing stores (three locations are available; see map). However, note that not all suits sold there are considered "smart" enough to trigger the next mission. To avoid unnecessary expense, using a suit already in Michael's wardrobe is recommended.

Therefore, utilizing an existing suit from Michael's closet provides the most efficient method for completing this prerequisite.
