Though the 'Old Farmer's Almanac' states that no one dresses better than Ed Begley Jr., you can at least try and get close to his level by hitting up downtown's Suburban Riot, which deals in urban-Cali cool and USA-made goods, most sewn within 20 minutes of Downtown L.A.
The this-is-how-you-wish-your-apartment-looked flagship store boasts choice in-house duds (French terry "Gentleman shorts", crazy-soft button-downs, Always Sunny tees they've been designing for the show since 2005, etc.) and accessories from brands like Raen.
Suburban Riot: 111 W. 7th St R1; 213-689-3271.
