Oh.. and as for your secondary rectangular shape: this is THE dress to EMBRACE the rectangular and ROCK it with confidence!!
There is no shape that is better or worse. It's all in how you wear it. And the cool thing is when you have a shape that allows you to transform your shape in any which way you happen to feel like it for that day. Far as I'm concerned....
*some days I'm inverted triangle, some days rectangle, some days hourglass.... and yes even some days I wear clothes to appear to be a pear, which is the exact opposite of my true shape... that's the miracle of fashion!
