I've found the MOST gracious DIY websites. No, it's not high school home making class... it's fun up to date fashion DIYs.
The one I'm totally in love with is this:
The top and skirt that's got the fashion world whirling. If you've read a fashion magazine in the past 2 month, you've probably seen that outfit. But now you can make the shirt your own!!
Viola! You've got yourself a Proenza.
I do want to give a try on this... my take would be a nylon/polyester long sleeve rather than a cotton one just because I think the texture/color will go better... but I'm not sure, we'll see.
