15% off at Organic Basics through 6/25 with code RONI15! The only whitening product worth buying plus the shirts worth maintaining. Oxygen bleach is the star. One long hot soak does what the viral fizzing recipe can't, because it pairs peroxide with the alkaline conditions it actually needs to work. My favorite tees: COS for a structured boxy fit, Buck Mason and J.Crew for a soft vintage feel, Organic Basics for stretch, and the $25 Uniqlo Supima for tucking in. Plus the long-sleeve and V-neck versions you've been asking for.
