About the Inverted Triangle Shape... You are truly a beautiful and a one-of-a-kind shape!  Your body figure starts broader on top and narrows as it gets down to your feet.  This is great to know because you can clearly see what styles work best for you.  Starting from top to bottom, you consider yourself to be top-heavy with broad shoulders, wide upper back, and full breasts.  These features can be seen as both an asset and as something that needs some deemphasizing.  So, focusing on the right styles is important when complementing your figure just right.  From waist down, your hips, buttocks, and lower legs become proportionately smaller; but your thighs definitely have some great shape to them.
As unique as you are, incorporate your shape knowledge into your shopping habits.  Keep it sassy and embrace your special inverted triangle shape.
