Another sale to apprise you of: Brooks Brothers Summer Clearance. Typically, I use BB as a model for old-school fit that you don’t want to emulate, even though their fabric and quality of their garments are very high. But, for business staples you really can’t ignore them, and you can still find some great things, provided you know what to look for.
So, if you need some high-quality, traditional dress shirts, sift through the sale, but look for things like what I’ve posted below (these are just examples, there are several more). They’re all the slim-fit (BB says up to 5″ off chest and torso), which should work on most body types. If you’re a bigger guy, you may want to go with the regular sizes, and get it tailored down. BTW, BB’s non-iron fabric is pretty amazing. I know fabric wonks think that non-iron fabric is subpar, but for real-world usage, you can’t beat it.
