Posh Shop multi-color suit size 1X

This suit is brand new, never worn. I purchased it from the online store, The Posh Shop, over a year ago with a specific purpose, but it doesn't fit me the way I'd like it to. Probably because I'm more of L than XL or 1X, if the clothing has stretch, which this does. I paid a little over $100 with taxes and shipping costs, so I'm selling it for $85.
