I bought an extra t-shirt from Hamilton in London that was too small for the person I wanted to give it too----it is an Adult Unisex Small (it's probably like women's medium, but in a unisex cut). A picture of the shirt can be found here https://twitter.com/hamiltonldnfans/status/938476716170891265?lang=en, it is dark blue with the gold stars on the front. It has the Hamilton logo with London written on the nape of the neck in the back. I paid 25 pds for it, so asking for $35 which will include shipping. Just want it to find a good owner!
