Either we want it or not, white is the least durable of all colors. You can keep your cotton shirts white as long as possible using Clorox and other bleach solutions, but truly there is not much you can do to preserve a white bra. Chlorine used in bleach can seriously damage the delicate fabric of a bra, non-chlorine solutions can work opposite to the desired effect. Fabric softener will definitely cause the yellowing of a white bra and hot water will cause discoloration of all elastic parts including rubber bands. As you may have noticed, the ongoing trend is black as a new white. Black and nude bras are widely accepted to wear under white casual or fashion tops.
Knowing all that, Lacy Hint's advice is: wear a white bra only if you have to and only when it is really worth it! The recommended Isabelle Jacquard and Lace Push up Bra has deserved the right to be within Lacy Hint's collection. This bra works as a piece of jewelry under a snow white top when you can't really opt for other color.
