Vintage shirts on-site

[Blanco]

I have seen those vintage (marled prints) Mickey Mouse t-shirts at shopdisney.com. While I love the colors and it is very tempting to purchase one before trip and it’s tax free, are there more colors available at the park?

The reviews aren’t spectacular as they tend to run big and disintegrate faster than a normal shirt but I’m willing to shell out $36.99 for a classic shirt and if they have XS in the park.

can anyone help and/or give opinions?

TIA!
