I wouldn't recommend a tunic top with an a line maxi - you will just create a big tent.
If you have great legs and boobs thats where you need to draw the eye, therefore I would recommend:
Knee length skirts (A line ok/ bias cut the best) not straight as if you have a thicker waist this will make you look boxy. You'll look better with a skirt which is sat lower on the waist, ie low cut not high cut, as this will make you look longer in the body and help breakdown your waist.
I would also recommend crops for this season, very on trend, and if you have good legs get them out! Wear with tunic tops which are fitted over the bust but then skim over your waistline.
Also look at empire line dresses, v neck ones, which draw the eye to your boobs, fit under the boobs and then fall away, again bias cut good for your shape and to the knee.
I will have a rummage for you...
