Thanks for all those who tried to answer. Got inspiration from the answer this link in case anyone gets into the same trouble as I did. Include intermediary (through model) in responses in Django Rest Framework.

class StyleSerializer(serializers.ModelSerializer):
    colors = StyleColorSerializer(source='stylecolor_set',
                                  many=True, read_only=True)

    class Meta:
        model = Style
        fields = ('name', 'colors')

serializers.py

class ColorSerializer(serializers.ModelSerializer):

    class Meta:
        model = Color
        fields = '__all__'

class StyleSerializer(serializers.ModelSerializer):
    color = ColorSerializer() # each style has a set of colors attributed to it

    class Meta:
        model = Style
        fields = '__all__'

class SizeSerializer(serializers.ModelSerializer):

    class Meta:
        model = Size
        fields = '__all__'

class StyleColorSerializer(serializers.ModelSerializer):
    size = SizeSerializer() # each style-color combination has a set of sizes attributed to it

    class Meta:
        model = StyleColor
        fields = '__all__'

Because your models are too complex, I’m afraid the code above didn’t fit that well.

To be more general, if you wanna attach the queryset of B model at the same time when you fetch the queryset of A model (which has a relationship with B model), you have to define the BSerializer() in the class of ASerializer().
