You can use a prepare recipe with a step to parse the date or the formula to create the month column. 

Also for black and white shirt you can

a)select a filter recipe

b) inside the recipe, select the column and filter for the categories you like

c) prepare recipe and a step to keep rows on value 

Hope it helps.
