Brooks Brothers is offering a sweet 25% off all purchases starting tomorrow 9.23 and ending 9.27. Consider it a chance to beef up your Fall wardrobe. Below are my top picks.BB-Levis collaboration. Opt for the darker wash in either 501 original straight leg or the 514 slim fit ($148), which runs a little narrower. Pass on the 505 regular fit. Their high rise will take you into dad jean territory -- a land best left unchartered..The Merino Zip-Front Vest ($89.50) might not exactly be a sock-knocker, but I assure you that you'll get tons of wear out of it this season. It's the perfect layering piece to toss on beneath a blazer on brisk days, and this shade of gray is universally flattering..Speaking of sweaters, if you felt like upping the ante, you could check out this Black Fleece Polo Sweater ($350). I love its unexpected details: grosgrain trim on the placket, button-down collar and five buttons down the front (two more than you'd normally see). It's all very Royal Tenenbaums..For cold weather, you can't go wrong with a wool necktie. Those in plaid or tweed above ($125) each are a great option. They're seasonally appropriate, and they'll also keep your neck warm. If you're a pocket square lover, pair textured neckwear like this with a silk square. The contrast of textures will make the combo visually appealing.A link to the F&F invite is below.Brooks Brothers F&F Fall 2010 Invite
