Nude & black plain underwear
These will go well under all clothing.
A great pair of dark blue jeans
If you get the right style for your shape, a pair of blue jeans can do wonders for your figure.
A "Go to" jacket (or coat)
Decide what works best with other items in your wardrobe. Often, longer styles will go with everything, while shorter styles can look more casual.
Ankle boots
If you find the right pair they can go with almost any outfit and make your legs appear longer and leaner at the same time.
