If you want to buy lingerie sets, the first thing you should consider is the color combination. This is because the right combination makes the apparel more attractive. Now, if you buy a matching set of black panties and a black bra, you still get a matched set but this is not what we are talking about here. Matching your colors in this context means you are buying intimate apparel with two shades of the same color. For instance, you can go for a light sky blue bra and matching deep blue panties. You can also buy light brown chemise and a deep brown under skirt.
The trick here is to choose the colors you love and blend them to your taste. If you are not too keen on blending colors just stick to one color. Buy a matching pair of white bra and white panties and you will be happy with the result.
