On Our Radar

Our web history is a testament to the fact that we tend to visit and revisit the same online shopping destinations on repeat. That's not necessarily a bad thing, but we're always excited when something new tempts us from the usual suspects — and thanks to this pretty Fall lookbook that landed in our inbox, A-Thread.com is shaking up our shopping routine. With its selection of classics intermingled with trendier fare, beautiful jewels, and cool accessories, all with very friendly prices (say under $140 for a great leather handbag or $79 for a silky button-down), this site is worth adding to your bookmarks now. And to sweeten the deal, A-Thread isn't just about looking good; each time you shop you're doing good, since five percent of your purchase goes to one of its four charity partners. In fact, it may be just the place to start your holiday shopping.

If you haven't heard the name Jessica Chastain, make a note because you will, and soon. The Juilliard-educated actress has seven movies expected to release in 2011, including one where she plays Brad Pitt's wife in the upcoming Tree of Life. Not bad for an unknown, eh? While we can't wait for this promising young thing to hit every big screen, we're already falling for her clean, ladylike style in real life. She sticks to a neutral color palette — all the better to highlight those red locks — and fitted, classic silhouettes that emphasize her gorgeous looks. Check out our fab slideshow of Jessica's best looks so far.

Ah, the secret contents of a woman's handbag — it's a little slice of our lives, which is why we love J.Crew's quirky handbag shop feature. It literally spills the contents of J.Crew employees' bags for all of us to see. First up for inspection is Kim, J.Crew's head bridal designer. You can roll over the items — like her elegant Bottega Veneta wallet — for a quote from Kim on why it's important to her. As it turns out, the woman who makes us want to get married a 100 times just to wear the white dress uses a stress ball. Who thought making wedding dresses could be anything but fun?!

Today is a fabulous day because a new fashion baby called Closetista was born. And here's why it's relevant to every style fan's life. A big part of the network is its daily video interviews with emerging designers and style makers. But what we really love is its shopping component, which offers limited-quantity designer pieces from future seasons; that way, you're way ahead of the fashion curve. Today's sales are Geren Ford and Jesse Kamm. Here's a sneak peek of the upcoming broadcast schedule, so get ready to watch, then spend. Oh, and Closetista will donate 10 percent of its launch week sale — that's now! — to three charities: The Smile Train, MS Society, and Dress for Success.

The only complaint we have with the latest in must-wear accessories is that everyone else is wearing them, too. Fortunately our newest must-have sunnies don't come with that problem. Prada's exclusive new PradaPrivate collection features the first-ever customizable eyewear. So you get gorgeous sunglasses, but with two removable plaques on each temple, featuring changeable letters, numbers, and symbols like hearts, stars, and skulls. Customize your shades starting Dec. 5 at Prada and Sunglass Hut, then, feel free to change them up as often as you like to avoid any style copycats.

It's no secret that Lindsay Lohan has had a hard few months — and now she was made fun of on Glee. But she's turning things around, and one of her latest projects is starting the 6126 Gold Member club. For $39.95 a month, you receive an item — hand-picked by Lindsay herself — valued at over $75, plus free shipping. It's a pretty good deal, so if you like her designs, sign up now. The first 10,000 members will get a free pair of 6126 leggings.

Project Runway alum Christian Siriano, along with partners Divya Gugnani and Mariah Chase, has launched a new ecommerce site — and it's changing the way we shop. The site, Send the Trend, offers on-trend accessories, all for $29.95, with free shipping. But, there's more — Christian and the site's directors hand-pick the merchandise themselves, then, using a "style-survey," help you customize and define your personal style to filter out what best fits your fashion sense. Whether you're a bohemian, glam girl, crave the classics, or like it a little edgier, your survey results will help to tailor your shopping experience. Amazing.
