Navy and Burgundy are always the perfect combination of dark tonal colors that can transition you from the brighter colors of your summer wardrobe into the rich dark colors in your fall outfits. A touch of floral is still ok but try not to add on too many other competing patterns.
Finally, make your outfit a tad more trendy with a coordinated tote. This will give you a bit more of this color mix and keep your pockets empty from unsightly bulges.
