White lace cardigans occupy a specific niche, dressed up enough for a summer dinner, casual enough to throw over a beach outfit, and the kind of thing that gets reached for constantly once it’s in your wardrobe. This one earns that versatility through its allover shell lace pattern, which creates an open, airy fabric that still has real structure thanks to the round yoke and scalloped hem. The styling concept here β lace over a white button-up, is one worth borrowing, and the pattern itself sits naturally alongside the lace going-out top with cowl neck for fans of white lace crochet.
Crochet Top Over White Button-Up
The cardigan is worked in repeating shell clusters throughout the body and sleeves, with the scallop edge built into the final hem row rather than added as a separate border. The round neckline is finished with a simple edging, and the button band runs down both front edges. For another shell stitch make that shows how versatile the pattern repeat can be, the bamboo yarn shell stitch ruffle top takes the same cluster format in a completely different direction.

Quick Stitch Guide
Sizing & Measurements
This pattern uses a repeating stitch profile that allows you to easily customize the fit:
Stitch Multiple: 10 plus 2 extra chains.
Sizing Tip: To customize the width of your panel to fit over your favorite white button-up, chain in multiples of 10 until the chain reaches your desired width (making sure to allow a little extra room for layering), then add 2 more chains before starting Row 1.
Written Pattern
Foundation
Create a slip knot on your hook. Crochet a foundation chain using a multiple of 10, then add 2 extra chains.
Row 1
Work 1 single crochet in the second chain from your hook.
Chain 5, skip the next 4 chains, and work 1 single crochet in the next chain.
Repeat the instructions from * to * across the entire row.
End the row by working 1 single crochet into the very final chain.
Row 2
Chain 1 and turn your work.

Chain 2.
In the center of the next chain-5 space, work a Shell Stitch: 3 double crochet, chain 2, and 3 double crochet all into that same space.
Chain 2, then work 1 single crochet in the next single crochet stitch.

Pro-Tips & Technique Explainers
Pro-Tip: Navigating Chain Spaces
When working into the “center” of a chain-5 space in Row 2, you don’t need to pierce the exact 3rd chain stitch with your hook. Instead, simply insert your hook underneath the entire chain loop (into the open space). This allows your stitches to slide naturally into the perfect center alignment and makes the pattern work up much faster!
Technique Explainer: Perfecting the Shell Stitch
The Shell Stitch used in Row 2 creates the beautiful, fan-like lace design. To keep your edges looking crisp against a white background, ensure your tension remains consistent on the “chain 2” sections. If you notice your shells pulling tight or warping the fabric, try loosening your chains slightly to give the double crochets room to bloom.
