Everyone has a signature color. Mine is toothpaste blue, which I try to find in everything from pajamas to T-shirts.
Despite my love of this hue, I still beseech brides to avoid choosing bridesmaid gowns in aqua. While one girl in an aqua dress isn't an eyesore, try five -- or eight. That's a lot of aqua. Shiny fabrics, in particular, make everyone look like they've been dipped in mouthwash and tossed out to sea. (Note: This is not to be confused with lighter shades of blue/green, which are usually very flattering and much less overwhelming.)
