17. You Need The Same Dress/Shoes In Three Different Colours
There is always going to buy one or a few items in your wardrobe that are always the same and you have it in a variety of colours. Whether it's a pair of shoes, a bag or a top - you need it in every shade of black that the store has to offer. It fits you perfect, it's flattering and it's easy to dress up or dress down. Why wouldn't you buy six versions of the same thing when it makes you feel like royalty?
