Easy Crochet Boho Top Pattern Free Made From a Granny Square

This crochet boho top pattern takes a classic solid granny square and turns it into a wearable, flattering piece with simple shaping and an adjustable finish. You begin by building a clean, solid square that determines the center of the top, then you add triangular side extensions to create the width needed for your bust. Because the side sections grow with easy increases, you can size this top to your body using measurements instead of guessing.

Crochet Boho Top

The edging adds decorative loops along the hem that can stay as-is for a lightweight look or become a base for fringe if you want extra movement. Long ties at the sides and neckline let you adjust snugness and coverage, making this a versatile crochet boho top for summer outfits, festivals, or layering over swimwear.

Notes

This top starts as a solid granny square that becomes the center of the garment.
You will turn after each row to keep the square straight and even.
Stitch markers are used to mark the four corner chain spaces so you always know where to place corner stitches.
The triangular side extensions are worked on only two sides of the square to build width.
Use measurements for the best fit. Stop the side extensions when the width equals half your bust measurement.
The bottom edging creates chain loops that can be left plain or used to attach fringe.

Sizing Guide

XS to S uses 7 square rows
M uses 8 square rows
L uses 10 square rows
The side extensions control most of the width, so you can still customize even if you choose a different square size

Each triangle is worked back and forth in rows and grows wider with increases

Triangle Row 3 and Onward

Repeat the increase row every row
Keep working until this triangle section measures half of your bust measurement across the widest part
Example from the tutorial 16 increase rows produced about 23.5 inches width

How to Measure the Triangle Width

Lay the piece flat
Measure from the outer edge of the triangle straight across to the center point of the square
Stop when this equals half your bust measurement

Repeat on the Opposite Side

Rotate the top and attach yarn to the opposite corner chain space
Work the same triangle setup row
Repeat the same increase rows until the triangle matches the first triangle in row count and width

Keeping Loop Spacing Even

Always place the loop into the same repeating position
Keep your chain 4 consistent and not too tight
If the hem starts to wave, loosen your chains or increase the number of plain sc between loops

Side Ties and Neck Ties

Side Ties

When you reach a side corner, chain a long tie length
Make the tie long enough to wrap around your waist and tie comfortably
Sl st back down the chain to the base to reinforce the tie
Continue crocheting along the edge after returning to the base

Neck Ties and V Neck Shaping

Continue the same loop edging pattern up the sides toward the neckline
When you reach the center V area, skip the center stitches to preserve the V shape
Resume the loop pattern on the other side of the neckline
