Gallery brand Vintage button closure, buckle knee length jacket coat size medium

This thing is a BEAUTY!!!! Gallery brand Vintage button up buckle knee length jacket coat size medium. I'm a 14/16 and I can get this on and wear it and look cute, but it's forced to be open, I am too big to be able to use the buckle or the buttons😪 Trust me, this would be in my closet forever if it were a little bigger. the lining is a soft pink, looks satiny. this is a yellowish cream, with pink, purple, greyish whitish accents. I would say it's pretty true to size, it might run a tad big.
