How to split CNN for different classification task

I'm working on multiclass a classification task. I want to use VGG 16-layer, where the first layer is responsible for the binary task (men or women), next 7-layers for example colour classification, and rest for what items are on image (for example: hoodie, t-shirt or pants). Summary I have about 280 attributes. How to write this convolutional neural network? Any example?
