Welcome, Jayne!!
Yours is a great idea. We have suggested a function like this to Greg and Angie and I believe they are considering it and/or figuring out how to make it work, but if you use the contact form to make that suggestion, maybe you'll get more details from the man himself!
In the meantime, do you feel confident that you have typed your body shape correctly? If not, please post pics and we can help you out, and if so, then you're off to the races!
If you read various members' posts and look at their pics you will soon learn who has a similar shape to yours. However, even within a shape there is SO much variation! So it's wise to consider height, proportions and colouring as well when considering what styles will best suit you.
One really fun function of this forum is that sometimes members with different body shapes will buy the same item and show it and we can see how it looks on various body shapes; a fascinating glimpse into the dressing room that probably none of us could get anywhere else! The Bailey 44 dress from Anthropology is a recent example; if you look for that in the archives you'll pull up lots of posts! And I (a slim hourglass/rectangle) have the same dress as Celia (anhourglass-pretty pear) and Kari (a taller curvy hourglass). It looks nice on all of us, but in a different way.
