Welcome to The Great Try-On. We're gearing up for fall, and that includes freshening up our wardrobes with some new pieces. We got to try on some of the best fall pieces from some of your favorite brands and documented it all from our at-home dressing rooms so that you can see how they actually look IRL. We hope that our photos and candid reviews will help you shop for fall wardrobe builders and trend-forward pieces that you'll wear over and over this season and beyond.

Australian brand SIR. has quickly risen to cult status among fashion insiders who can’t get enough of its easy, effortless pieces. The brand specializes in an undeniably cool take on resortwear that Bondi Beach is known for, with styles ranging from tailored suiting to floral dresses to swimwear. It has a knack for designing the type of clothing you’ll want in your closet for everything from the office to a holiday, so it comes as no surprise that I spotted its pieces this summer on stylish vacations, as go-to wedding guests dresses, as well as in back-to-the-office looks.

I tried out some of the pieces from SIR.'s latest collection that tap into my personal style, which blends classic and modern designs. To say that they won me over is an understatement, and I already wore some of them during events for New York Fashion Week. Ahead, see exactly what I would recommend buying from SIR. right now.

SIR. Lucelia Cut Out Midi Dress

My review: I originally spotted this dress on a friend who wore it to a wedding abroad over the summer and instantly flagged it as something to add to my closet. I've been on the hunt for a long, elegant dress for events, and this piece is exactly that. Designed with floss straps and cutouts along the back, it taps into the current trends but is timeless enough to have in my closet forever.

What I love most about it, though, is that while it is dressy enough to wear to an event, the cotton-and-silk material makes it less formal than something I would reserve for a black-tie event, meaning I can wear it more than just for those rare occasions.

SIR. Clemence Vest and Tailored Shorts

My review: Tailored vests are one trend I can't get enough of, and SIR. has the perfect take that makes it a go-to piece for the office or the weekend. The linen material makes the style feel more relaxed than something that would be reserved for corporate dress codes, making it something I would opt to wear for brunch over the office.

While I already own several pantsuits with matching vests, I love this take that has coordinating shorts—the missing piece I've been looking to add to my L.A. wardrobe.

SIR. Adrien Strapless Bustier and Trousers

My review: While black is the go-to color you'll find heavily stocked in my closet, this season, I also can't enough of rich chocolate-brown shades. There is an element of warmth and richness that makes it a great neutral shade if you're looking for something other than black or beige.

While SIR. has many designs in chocolate brown, this set, in particular, caught my eye. I'm always drawn to cool takes on suiting and think that this bustier paired with slouchy tailored trousers feels fresh for fall.

SIR. Maxe Strapless Mini Dress

My review: With the return of '90s minimalism on the runways, I've been in that mindset recently and have been gravitating toward all things strapless, sleek, and pared-back. So when I saw this dress, it was love at first sight. This minidress could have been plucked straight out of the '90s yet feels very modern and of the moment at the same time.

Perhaps the thing I love most about this dress is the hourglass shape, which makes it feel more elevated than a similar style would if it were skintight. Here, I'm styling it with kitten heels, but I also wore it with a pair of strappy flats—proof of just how versatile the piece is.
