Looking for a dress blues cadet jacket

[capPA]

Hello, my first post, so my apologies if I post incorrectly.  I'm trying to find a 38L (or in this range) dress blues cadet officer jacket.  My son quickly grew out of the jacket his squadron gave him and they don't have another in this size range.  I tried Vanguard (they don't sell them), I called the nearest base (they said no...), I am checking out Ebay - just wanted to know if this group had any other suggestions?  I will check out the "marketplace" page on this site as well.  Thank you in advance, I'm at a loss as far as other options.

If you intend to use hook-and-loop for the shoulder boards, enlisted jackets tend to be less hassle
and they are less expensive.
