(this is Kay, who answered your other question with a pointer to a Simplicity pattern. Yes, the Simplicity and your example are both princess seamed patterns with the skirt portion flared. Very easy to do from a basic princess sheath type pattern, but I was unsure of your level of expertise in pattern-bashing.
If you're going to DIY from a straight princess pattern, add equal flare to all skirt sections, starting at the same level, or you'll wind up with a skirt that hangs funny.
Damn shame when spring reufess to show her pretty face it\'s been bucketing off and on here in Bris for weeks. So confusing but I love layers so I\'m happy to ward off our next steamy summer. It\'s a damn shame for you today tho\' this outfit is extraordinarily wicked:). I love the colours and textures of the top and scarf set off against the flirty metallic skirt. Just gorgeous.
I guess finding uesful, reliable information on the internet isn't hopeless after all.
