Blake Lively kicks off New York Fashion Week in the most subtle but chic way yet. See the sequined accessory the actress is praising that helped tie her look together.

The Gossip Girl alum took to Instagram Stories on Tuesday, Sept. 7, to show off her gorgeous sequined accessory, which she also humorously credited with upping the ante on her casual look. "@chanelofficial thank you for the birthday bag," she wrote as the caption to the video. "You really elevated my 'toddler chic' look." And since New York Fashion Week officially kicks off today, Sept. 8, we're hoping to see a lot more looks where that came from.

After giving her pink, black and grey bag a few note-worthy seconds of camera time, Blake also gave fans a glimpse at Mouse-adorned sweatshirt, distressed blue jeans and white sneakers.

alum's showstopping accessory is just the latest of gifts the actress received for her 34th birthday in late August.

Just a few weeks back, the actress also gave her Instagram followers a peek at the "early birthday present" she received from Louis Vuitton, noting she was "in love" with her new bag.

Anyone familiar with the mom of three knows that Blake's looks are usually far from preschool-chic, since the actress has stunned red-carpets and Fashion Week appearances for years, and we're talking about more than just Serena van der Woodsen's wardrobe.

While we wait to see what look Blake will turn heads with next, let's take a look at some of her most impressive Fashion Week appearances below:
