We all love a good striped t-shirt or tank, but sometimes it's nice to dress up your stripes just like Mandy Moore did at a forum in Washington DC. Mandy wore a retro-inspired striped Issa London dress with a full skirt for a ladylike feel, then made things sleek by topping it with a cropped black blazer and finishing with black patent cutout booties. This look is appropriate for the office and can just as easily for work at night. If you prefer a more colorful look, this striped colorblock shift dress from Asos ($75) or this Ted Baker colorful striped dress ($264) are more up your alley. Don't forget to top your stripes with a black blazer for extra sharpness and finish off with the right shoe for the occasion.
