Query: This is a beautiful coat but it runs very small

I truly wanted to keep this coat but it's too small. I ordered a size "L" and I normally wear a "M". I could barely zip it up. The zipper was stressed. Forget about wearing a sweater under it. There's no room! I'm 5'6" and weigh 155lbs. It has two deep zippered pockets on the sides and two deep pockets inside (one of them has a zipper). I don't want to return it but there is no way I'll ever fit into it. I can't exchange it because they don't have this color left in a larger size so I must return it. Be forewarned, this coat runs very small, especially in the chest. This coat was made for someone with a very small bust.
