Not really. My armor was bought from MM also. Forcefield is pretty thick stuff. https://moskomoto.com/collections/apparel/products/forcefield-ex-k-harness-adv-1 Based on my size and shape (6'2" / 220lb), I have a closet full of XL Tshirts that fit me just comfortably loose but not baggy. So I ordered the workhorse in an XL and it fits and hangs over my armor similar to my XL t-shirts I wear daily. If I wanted to wear the workhorse without armor I would definitely order a Large size as the XL would look like I was wearing a tent. Hope that helps.
