This outfit is quite simple but the reason why it shines is because of the colors. Picture it in a black block or just in browns and although pretty, it would be not too interesting. About the bra, I know it is totally out of the palette of colors, but wanted to add a little contrast to add a "dangerous" detail, specially between all the soft colors (I can be a little bit bad too!).
