It makes a big difference to the overall look of an outfit when you wear a white camisole under a white or cream button down, blouse, knitted top or piece of knitwear. It makes your white top look richer, crisper and whiter. The result is a more polished appearance.
I see many women wearing nude or white bras under their white tops and nothing else. Although the color of the bra works, it doesn’t look so fab. White tops are usually more transparent than other colours and the addition of a white cami gives the top the appropriate coverage and extra visual interest.
I’m all for creating contrast, but I don’t fancy the look of other colours under white. It never looks quite as magical as the crisp, clean impact of white on white.
