Should I sell my old OCP tops to help buy new ones if they fit too large?

Good afternoon everyone. I have an issue regarding my current set of OCP tops. I have lost a considerable amount of weight since first being issued my OCP’s 2 years ago and my OCP tops now fit me large, to the point where I can grab all of the extra slack and fold it across my whole torso from one side to the other. The bottoms of the OCP coat also drapes down all the way past the top of the side pockets on the bottoms of the uniforms. It is also noticeable that I have a large amount of arm and shoulder room while in uniform. Overall I believe this presents a somewhat less sharp and less professional of an appearance than if I had a size down. I was considering just buying 4 new OCP tops of a better size and fit and selling/giving away my old tops, all of which are in good condition and two of which I don’t think I have ever worn as I generally alternate between just two tops. I am just curious if there is anything against any regulation which says that I cannot do this or if you all think there is a better plan of action? Thank you all for any advice.
