Most of the designers do produce larger sizes but what they send to the store is the trend of what sells the most I help with the processing of the truck someone boxes do come in the company that produces the product itself really controls what the store gets they do send a lot of medium and large is very few extra large or larger depending on the designer the stores do also have a feature where you can look online you may also call I would just suggest early in the day
Most you have order in advance if the store don't have it. So, don't feel discouraged about you don't see on display.
