One of the most extensive customization features in Sonic Forces is the vast array of clothing and accessories available for your custom Avatar. These items are purely cosmetic, meaning they do not affect your Avatar's stats or abilities, but they allow for incredible personalization. From hats and glasses to full outfits and shoes, you can truly make your hero unique. Collecting these items is a major incentive for completing various in-game activities.

Acquiring Clothing & Accessories:
- Story Progression: Completing certain story stages will unlock basic clothing sets.
- Extra Missions: Many Extra Missions specifically reward you with unique clothing items upon completion. These are a primary source of new gear.
- Daily Missions: Daily Missions frequently offer exclusive clothing items as rewards, encouraging you to check in and complete them regularly.
- SOS Missions: Rescuing other players' Avatars in SOS Missions will reward you with a piece of clothing that the rescued Avatar was wearing, often leading to rare or unique items.
- Red Star Ring Collection: Collecting all five Red Star Rings in a stage can also unlock special cosmetic items.
- DLC: Additional clothing packs were released as downloadable content, offering themed outfits (e.g., SEGA/Atlus Pack, Shadow's Outfit).
Customization Categories:
- Headwear: Hats, helmets, headbands.
- Eyewear: Glasses, goggles.
- Body: Shirts, jackets, full outfits.
- Gloves: Various glove styles.
- Shoes: Different types of footwear.
- Aura: Special effects that surround your Avatar (less common).
You can change your Avatar's clothing and accessories at any time from the Avatar customization menu. Mix and match different pieces to create your perfect look. The sheer volume of available items means you can spend hours perfecting your hero's appearance. Collecting all the cosmetic items is a significant part of the game's completionist appeal.
