It's hot as New York in August here in New York in August. Nobody feels like getting dressed up, or even dressed for that matter. The city is awash in tiny solid color Summer dresses or tees and jean shorts.
To me this shot isn't about if this look is perfect, but about the inspiration of doing a lot with a little. Actually I look at this and think about color mixing. If you kept the shape of all these pieces but each was a different color, or even shades of the same color - with or without the patterns.
Looks like this remind me that in Summer, even though we are working with fewer layers, we can still have fun playing with pattern.
