I would check out this site for a wide array of fun options

I have this dress and I LOOOOOVE it. Super versatile. I can wear it as a tunic over leggings or jeans or dress it up with heels. It's from a great designer in Portland who will custom fit it for you.

I have this dress in a houndstooth and it's the only dress I've worn year-round and despite weight fluctuations - so comfortable, great investment, and a talented Canadian eco-designer. Fabulously sexy and fitted little black dress in a gorgeous, high quality - medium to thick doubleknit jersey. This dress is made to show off

This is pretty...also a south african online store, located in capetown. They have quite a few nice options :) what is your style, color preference? Dress with pleated cowl neck detail at back, ruching detail at sides Length: Short-sleeved Neckline: Boat neck at front, cowl neck at back Leg Shape/Hemline: below the knee Product code for your reference: A24000000097

ASOS usually is a great place to look for dresses as they have such a wide range of styles. This one could be a great option for your wrap party - it's trendy and feminine without showing too much flesh. I believe the flowy cut should be flattering. It is available in a classic cream/black combo (which will accentuate your upper body) or in black/pink (which will draw attention to the lower part of your body). Plus you can accessorise as you wish. You might find that shipping costs to SA might get you a little bit over budget if you choose express shipping, though. Hope that helps!

Since you don't wear a lot of dresses, buy one that you can wear to multiple things and create new looks with using accessories. This one is feminine and figure flattering.
