Lightweight, airy, and about as forgiving as a summer make gets — this tank drapes in soft granny-stitch rows that let the breeze right through. The gently pointed hem gives it a relaxed, floaty finish, and thin straps keep it feeling like nothing on a hot day. It’s a proper beginner project, worked flat in a simple repeat you’ll have memorized by the second row. If open, easy tanks are your summer uniform, this airy Mira tank shares the same weightless spirit.
Breezy Crochet Tank Top
Because it’s built on repeating clusters with open spaces between, the fabric stays cool and drapes beautifully instead of sitting stiff — and there’s no shaping to fuss over, just rows until it’s the length you like. Layer it over a bralette or a fitted cami and you’re set. For another lacy, throw-on-and-go option, this lacy summer-essential tank lands in the same easygoing category. A drapey cotton or cotton blend gives the best flow here.
What This Pattern Creates
This granny square tank top is lightweight, breathable, and ideal for warm weather layering. The open stitch pattern allows airflow, while the diagonal square placement gives the garment movement and drape. Because the sizing is controlled by square size rather than stitch counts, it is easy to customize.

Stitch Guide for This Pattern
Create Four Granny Squares
- Start with a magic circle
- Chain 3 to count as the first double crochet
- Work 2 double crochets into the magic circle
- Chain 1
- Work 3 double crochets into the circle
- Repeat the chain 1 and 3 double crochets two more times
- Chain 1 and slip stitch to the top of the starting chain 3
- Chain 3 to begin the next round
- Work 2 double crochets into the same chain 1 space
- Move to the next chain 1 space and work 3 double crochets chain 1 and 3 double crochets
- Repeat this corner pattern in each chain 1 space
- Slip stitch to join the round
Continue working additional rounds by placing 3 double crochets in each side space
- Work 3 double crochets chain 1 and 3 double crochets in each corner space
- Stop increasing when the square fits from underarm to midsection when held diagonally
- Make four identical squares
Square Sizing and Fit Guidance
- Holding the square diagonally is essential.
- The measurement from one corner to the opposite corner should comfortably span from under your arm to the middle of your torso.
- If the square is too small, the neckline will sit too high and the armholes will feel tight.
- If it is too large, the top may feel loose at the bust and underarms.
- Focus on body fit, not round count. Everyone may end on a different number of rounds, and that is expected.

Assembly
- Lay the four granny squares in a two by two grid
- Mark the halfway point of each side facing the center
- Using a tapestry needle whip stitch the squares together from the outer edges toward the markers
- Leave the center cross section open to form the neckline
Assembly Clarity and Neckline Formation
- The open center is what creates the neckline.
- Stitching from the outside edges inward gives you control and prevents accidentally closing the neck opening.
- The stitch markers act as a clear stop point so the opening stays even on all sides.
- This method keeps the neckline centered and balanced.
Neckline and Straps
- Switch to the 6.5 mm hook
- Join yarn near the neckline opening
- Single crochet evenly across the top edge
- At the top peak of a square chain 50 or your desired strap length
- Slip stitch the chain to the matching peak on the back square
- Turn and single crochet back along the neckline
- Single crochet two stitches together at the center join to shape the V neckline
Strap Length and Neck Shaping Notes
- The chain length determines how the top sits on your shoulders.
- Longer chains create a lower neckline and looser fit, while shorter chains lift the top and provide more support.
- The single crochet decrease at the center join subtly sharpens the V shape without making it too deep.
Underarm & Bottom Border
- Join yarn at one underarm seam
- Single crochet along the edge and into each chain of the strap
- Continue single crocheting down the opposite side
- Single crochet two stitches together at the underarm join
- Join yarn at any point along the bottom hem
- Single crochet evenly around the bottom edge
- In each bottom corner chain space work single crochet chain 1 single crochet
- Single crochet two stitches together where squares meet
Border Purpose and Structure
- The border does more than finish the look.
- Single crochet tightens the edges, reinforces stress points like the underarm joins, and helps prevent stretching over time.
- The small chain spaces at the corners allow the hem to sit flat rather than pulling inward.
Beginner Notes
- If this is your first wearable granny square project, take your time with square sizing and assembly.
- A well sized square makes the entire garment easier.
- Blocking the squares lightly before assembly can help them align neatly, especially if your tension varies slightly.
Troubleshooting
- If the neckline feels too tight, remove a round of single crochet or lengthen the straps.
- If the underarm area feels bulky, ensure you are only decreasing once at the seam.
- If the bottom edge flares, reduce the number of corner chain spaces on the final round.
Small adjustments go a long way with this construction style.
Final Step
- Weave in all loose ends
- Try on and enjoy your breezy granny square tank top
