#21 - Universitario 2013 88th Anniversary Shirt by Umbro

And so we come to another limited edition shirt on this list (yet again nominated by me), though this one encountered very little resistance due to its staggering beauty.

Released to celebrate Peruvian club Universitario's 88th year (oh come on, since when has that been any kind of event?), Umbro stripped things right back and went full-on retro.

Despite being a very minimal design, there are several features that make this shirt great. Firstly, the whole thing is constructed from Umbro's lush cotton used on so many of their 'Tailored By' range.

And then there's the details. Starting from the top, we find a neat, trimmed collar which then has a neck opening that extends almost all the way down to the abdomen; a brave move given how most manufacturers still try to keep their tribute shirts within the bounds of modern features.
