Birkenstock Boston - I went down one size and took a size 41 (8-8.5). I have other Birkenstocks that are size 42 (9-9.5), but I found the Bostons fit a bit long
Gap Oxford Big Shirt - fits quite oversized, boxy fit. Ordered a medium and had to try and shrink it in the dryer. Fit better after that
LF hat - classic dad hat, great quality
