Is it possible to use different choices for subclasses of models? The following code should give you an idea 

class Clothing(models.Model):
    size = models.CharField(max_length=1)
    colour = models.CharField(max_length=1)

SHIRT_SIZES = {
    'S','Small',
    'M','Medium',
    'L','Large',
}

class TShirt(models.Model):
    size = models.CharField(max_length=1, choices=SHIRT_SIZES)

MENS_CHOICES = {
    'K','Black',
    'R','Red',
    'B','Blue',
}

class MensColours(models.Model):
    colour = models.CharField(max_length=1, choices=MENS_CHOICES)

class MensShirt(MensColours, TShirt):
    class Meta:
        verbose_name = "men's shirt"

WOMENS_CHOICES = {
    'P','Pink',
    'W','White',
    'B','Brown',
}

class WomensColours(models.Model):
    colour = models.CharField(max_length=1, choices=WOMENS_CHOICES)

class WomensShirt(WomensColours, TShirt):
    class Meta:
        verbose_name = "women's shirt"

The reason I'm using mixins is that I have attributes/choices that can be shared between different models (e.g. also having women's/men's pants, which may have the same colour choices but different size choices than the TShirts). Overall, however, all clothing has a colour and a size.

How should I do this?
