I love this look! But yeah, the Tory Burch "Sandy" sweater is $348 at Shopbop.com, so let's start looking for some budget-friendly alternatives...
I found a couple options that might work. First up, LOFT delivers this great look for less - it's sold out online (was $64.99) but still available in some stores. You might be able to layer it over a white shirt to recreate the look of the white collar on the Tory Burch style.
Also from LOFT, there's this lace front cardigan ($59.50) that will give you a very similar feel, but in a different silhouette:
Speaking of cardigans, check out this find from Joe Fresh at JCPenney.com for just $39! I haven't seen it in person but it looks amazing online:
If you're not wed to the navy blue color, there's this crochet front sweatshirt at Forever21.com for $24.80 - I actually just picked one up for myself this week and I love it (here's the photo I posted on Instagram). The crochet panel looks well made and feels modern paired with the casual sweatshirt.
Another option also from Forever21.com is this Garden Terrace Pullover, just $17.80. It features a black lace panel contrasted against a gray sweatshirt:
There's also this Apt. 9 lace front sweatshirt at Kohls.com which comes in gray/cream, navy or black. I saw these in person, too, and thought they looked really nice for the price! (Again, here's my Instagram photo so you can kinda see how it looks in real life.)
Hopefully one of these options will fit the bill! Got a suggestion for Lauren? Let her know in the comments!
