1. Mr. Olive
I find Mr. Olive to be fantastic for denim, shorts, sweaters, hoodies, outerwear, and leather goods.
2. Lad Musician
I love Lad Musician for their well fitting high quality tees-- I have tried a lot of other brands and none of them look better on me than Lad. Also, Lad's fabric quality is second to none and puts W+H tees to shame.
I like W+H shirts and outerwear, but I have never had very good luck with their bottoms. All of their shorts and pants seem to baggy in the thighs relative to a tight fitting brand like Mr. Olive.
This brand has some very interesting tees due to how they constantly very their fabric blends with each season. Many of their tees often contain a blend of something like silk, rayon, or even wool sometimes.
Have only ever bought the pants from Julius. I think their shirts look too unusual, but I really like the fit and look some of their pants. You can definitely wear some of this stuff without looking like a goth ninja. Many of their bags and leather jackets are very nice too.
