I've been in Austin, TX for the past couple of weeks and I came across this amazing store called Bows + Arrows on S. Lamar St. This shop features some of the best menswear that I've ever come across and they keep the other half of the store for the ladies. Some of the key brands they features are Band of Outsiders, Apolis Activism, Nice Collective, A.P.C., Shipley & Halmos, Rag & Bone, Trovata, Steven Alan, and Rachel Comey Men's Shoes. Lauren, the girl who runs the store, is super friendly and willing to help no matter what your needs are.
I ended up picking up a really nice blue officer's shirt by Apolis Activism (shown above) and I sure hope to be back for more. Bows + Arrows also has a good online shop and you can check it out here
