One of my favorite online stores for casual clothing, Bench & Loom, just started a clearance sale. Prices are now discounted by up to 70%. They seem to have a sale section, but not everything is included on that page, so you may want to check around the different categories to see if there’s something for you.
Some particularly attractive prices include these $89 selvedge denim jeans by Tellason (both the Ankara and John Graham Mellor models), $39 1950s-style white t-shirt by Levi’s Vintage Clothing (note, this has very short sleeves), $57 grey sweatshirt by Levi’s Made & Crafted, and $39 belts by Tanner Goods. And although they’re not cheap by any measure, these Brooks England jackets are amazing (available in both cinnamon and grey) and this is the lowest I’ve seen the price go.
