Perhaps set up a sales kit (if quantities are consistent), or script a solution (button script to add extra lines based on your business logic).

Ooh, button script sounds interesting! I'll look into that. We have the BOM module implemented, so Sales Kits is disabled, but I'll ask our support guy if we can have both. Thanks!

BoM replaces the Sales Kit functionality.  The same idea applies to BoM, with the same limitations.

A pseudo kit (miscellaneous code) and event script could work too (instead of a button script).  When a code is added, look up associated items (in a UDT?), and add them to the order.

Let me rephrase this. I agree with Kevin. Go to Inventory and create a Kit item for the Style and then go to BOM and create a Kit type Bill using the Style item from inventory with each size being the components
