Chef Works JLCV-BLK Montreal Cool Vent Basic Chef Coat, Black, 2X-Large

Is this item a three pack?

The seller answered a previous question from another buyer and said it can be embroidered. my question is how do i order this with embroidery?

so are the sizes accurate?. boyfriend wears XL or 2xl but don't want to order the wrong size

Can i have this item embroidered ?
