Lizard Lounge for sure. There's a Filson store a few blocks from there too which is nice. Winn Perry. Very very small store off the beaten path kind of in SE. Nice, but they have everything on their website. The space is like 200 square feet maybe. Seemed that way. Michael Allen's is nice if you're downtown as well.
http://michaelallensstyle.com/clothi...ier_store.html They had some cool funky-ish merchandise besides their custom shirts and formalwear. I dropped in last time in town, friendly staff. Powell's bookstore. Must visit. Blakes for Jeans. Cargo isn't a clothes store but its a very funky "import" store where you may find some cool chinese themed merchandise. Its a block from Filson.
http://www.cargoinc.com/ I also found that the Saks 5th Ave Outlet at Bridgeport Village was a really good one (the saks in Downtown Portland closed)...but they had some really good merchandise and prices there, at least when I went there about a month ago. If you're out there, you might want to check out Mario's 310.
