- Crochet Hook: 3.0 mm (or size to achieve a firmer fabric and gauge).
- Stitch markers
- Darning needle
- Scissors
Special Stitches

Stitch Abbreviations
- ch: chain
- sc: single crochet
- dc: double crochet

- st(s): stitch(es)
Useful Tips
- Always use stitch markers at the center/top of each cup and at the edges to keep shaping even.
- Using two strands ensures the cup stays opaque and holds its shape.
- Make two identical cups for a single bra.
- Firm edges and straps keep the bralette secure and comfortable.
- To change the size, add or subtract base chains or work additional rows for larger cups.
Pattern Instructions
Triangle Cup (Make 2)
Cup Foundation
- Using 2 strands of yarn and your 3.0 mm hook, make a slip knot and ch 13 (for a standard cup).
- Row 1:
- dc in the third ch from hook (first “dc” group).
- dc in each ch across until the end (you will have 11 dcs).
- In the last ch, place 3 dc (increases for the corner/point).
- Place a stitch marker in the center dc of the 3-dc group (this marks your cup tip).
- Working on the opposite side of the foundation chain, dc in each ch until you reach the starting ch.
- You should now have a symmetrical “triangle” base.
- dc in the third ch from hook (first “dc” group).
- Row 2:
- Ch 1, turn.
- dc increase (2 dc) in the first st.
- dc in each st up to the center st marker.
- In the marked (center tip) stitch, 3 dc (place marker in new center dc).
- dc in each remaining st; dc increase (2 dc) in the last st.
- Rows 3–14:
- Repeat Row 2, always working dc increases at the first and last st, and 3 dc at the center-tipped st.
- Move marker as needed.
- Continue until the cup measures approximately 6 inches from base to tip (or as desired).
- Fasten off and weave in ends.
Tip: For larger sizes, add more rows; for smaller, stop earlier.
Edging the Cup
- With hook and working yarn, rejoin at the lower side of the cup.
- Ch 1.
- sc evenly all around the cup edge to the lower base. Work one sc in every row end and three sc in the tip/point.
- When at the base, sc across the lower cup edge (1 sc in every dc st).
- Continue until you reach the stitch you started from, sl st to join if needed.
- Fasten off.
- Ch 1.
Repeat for Second Cup
- Work the second cup exactly as the first.
- Ensure both cups are the same size and shape.
Bottom Band and Joining Cups
- With RS facing, join cups at the base with sc or sl st as follows:
- Align cups, overlap slightly if needed, and use stitch markers to keep in place.
- Join at the corners and middle for stability.
Bottom Band (Optional):
- From one cup edge, ch enough for band extension (e.g., 14 ch for a moderate back tie).
- Continue with sc across the base of both cups and ch stitches, creating a stable band.
- Ch similar amount at the other end for symmetry.
Strap Construction
Neck Straps (for each cup)
- At the cup tip, rejoin yarn.
- Ch 100–120 (or as long as desired for over-the-shoulder/neck wear).
- Sc (or sl st) back down the chain to thicken it (optional for durability).
- Fasten off. Repeat for second cup.
Back Straps
- At the base corners (outer edges or band ends), ch 100 for each tie.
- Sc (or sl st) back down the chain for a strong strap.
- Fasten off and weave in all ends neatly.
Edging (Optional Row)
- Add a decorative edge (scallop, picot, etc.) or do a simple extra sc round all over for increased durability.
Assembly and Sizing
- Place cups side by side, join at the base, ensuring symmetry.
- Try on the bra and adjust straps as necessary for support and comfort.
- The band and cup height may be expanded for fuller coverage or a snugger fit.
- Weave in all yarn ends securely.
Conclusion
This classic triangle bra is designed for versatility and comfort. By working with two strands and using systematic increases, it delivers secure coverage and shape. Top and bottom edging provide strength and neatness, while long straps and a sturdy lower band guarantee adjustability. The design may easily be embellished, lengthened, or styled as a swim or fashion top, ensuring a flexible foundation for all sizing and creative adaptations.
