I ordered Adult Medium which is what my teenager usually wears and it was way too large so then I ordered the Adult Small which was unfortunately too small (sort of a Goldilocks moment!).
Despite this, I want to stress how pleased I was with Miami Heat Store. I had reached out to the store via email about needing to make the switch and it was close to Christmas and I was worried the new item would not arrive in time. MHS was so responsive and kind and professional and sent the replacement so quickly. I really was impressed with their customer service!
