The little black dress is definitely an essential piece that should be in every lady's closet because it has diverse function. It can be worn to any event with the right accessories. You can wear an LBD (little black dress) to the office, church, meetings, parties etc. I don't even know how many black dresses I own (like most women) and I usually just change the accessories out for different occasions.
I also would use colorful accessories to make a bold statement. For example when I wear black, I would accessorize with silver, gold or other fun colors. I would hardly wear all black. I think wearing all black is very safe and predictable and you can get lost in the crowd but when you play the look up with fun and colorful accessories, you will stand out in a good way in the crowd or an event. The purpose is not to call attention to yourself all the time but to show to people that you are different. You are unique and you are you!!
