The best bikini bottom sewing pattern depends on your preferred rise, size range, and how much mix-and-match flexibility you want. McCall’s M8502 is a clear choice for high-rise bottoms with a gathered V front and back; Style Arc’s Hamilton offers high- or low-waist options; and McCall’s M8329 includes a high-cut bikini bottom. The patterns below also include broader swimsuit sets for sewists who want matching tops or other cover-up pieces. Check the pattern’s size chart before cutting fabric.

McCall’s M8502 High-Rise Bikini Pattern
Best for: Sewists who want a high-rise bikini bottom with visible gathering and a matching cover-up option. This McCall’s packet includes sizes 4–12, pattern pieces, illustrated instructions, sizing information, and guidance on selecting fabric and trims.
The bottoms have a ruched V-shaped front and back. The packet also includes a front-knot bikini top with adjustable straps and a back tie, plus an elastic-waist mock-wrap skirt with side gathers. These coordinated pieces make it useful for sewing a matching swim outfit rather than bottoms alone.
Why it stands out: The bottom’s rise and ruched V detail are specifically described, making the design easier to compare with more general swimsuit patterns. Limitation: The listed size range ends at 12, so check the included size chart if you need another size.
McCall’s M7168 Swimsuit Pattern, Sizes 6–14
Best for: Sewists shopping within the listed A5 size range of 6–14 who want a McCall’s swimsuit pattern with pattern pieces and sewing instructions. The product information confirms that it is a swimsuit template, but does not describe the specific bikini-bottom cut or rise.
This pattern is worth considering when the available size range fits and you are open to reviewing the envelope or pattern illustrations for design details. Its listing is more limited than options that explicitly identify a high-rise, high-cut, or adjustable waist design.
Why it stands out: It provides a defined multi-size range and includes instructions. Limitation: The supplied product details do not specify the bottom style, so verify the pattern artwork before choosing it for a particular silhouette.
Simplicity S8932 Vintage Swimwear Pattern
Best for: Sewists who want a vintage-inspired set with multiple garment options. The listed designs include a bikini top, shorts, wrap, skirt, and coat. Pattern pieces and illustrated step-by-step instructions are included, along with suggested fabrics and notions.
The shorts offer an alternative to a conventional bikini-bottom shape, while the additional pieces let you sew coordinating layers. The listing contains conflicting size information: the product name says sizes 4–12, while the feature text says sizes 12–20. Measure and confirm the correct envelope or size chart before purchase.
Why it stands out: It offers several related swimwear and cover-up designs in one pattern. Limitation: The size-range discrepancy needs to be resolved before selecting a size.
McCall’s M8329 High-Cut Bikini Pattern
Best for: Sewists looking for a high-cut bikini bottom in sizes 14–22. The pattern packet includes templates, fabric recommendations, sizing guides, pattern pieces, and instructions. Its listed swimsuit set also includes two strapped tops and a one-piece swimsuit.
The high-cut bottom is the clearest reason to choose this option over patterns with unspecified bottom silhouettes. Gather details and ring embellishments are noted for the swimsuit set, though the listing does not say exactly where each detail appears.
Why it stands out: It combines a clearly described high-cut bottom with a broader size range and multiple swimsuit views. Limitation: Choose another pattern if you specifically want a high-rise or low-rise option, since those alternatives are not stated here.
Style Arc Hamilton Mix-And-Match Swim Set
Best for: Sewists who want a choice of bottom rise and leg line. This paper pattern covers sizes 10–22 and includes one- or two-piece swimwear options, high- or low-waist bottoms, and high- or low-cut leg lines. It also offers different neckline and crop-top options, including a D+ cup crop/shelf option.
The listing calls the pattern medium difficulty and specifies swimwear fabric with four-way stretch of 40–65%. It describes lining and gusset options, giving sewists choices when planning construction.
Why it stands out: Its stated rise and leg-line variations make it more adjustable in silhouette than patterns with one described bottom cut. Limitation: The medium difficulty rating and stretch-fabric requirement may not suit someone seeking a basic beginner project or a pattern for non-stretch fabric.
Buying Guide: Choosing A Bikini Bottom Sewing Pattern
Which rise and leg cut do you want?
Start with the shape you plan to sew. M8502 specifies a high-rise bottom with a ruched V front and back. M8329 specifies a high-cut leg. Hamilton offers high- or low-waist bottoms and high- or low-cut leg lines. For M7168, the supplied listing does not describe the bottom shape, so check the pattern illustrations before buying.
How should you compare size ranges?
Use body measurements and the pattern’s size chart rather than relying on ready-to-wear size labels. The listed options cover different ranges: M8502 lists sizes 4–12, M7168 A5 lists 6–14, M8329 lists 14–22, and Hamilton lists 10–22. S8932 has conflicting size information in its listing, so confirm its actual range first.
What fabric and sewing details should you check?
Swimwear patterns require attention to fabric recommendations and construction instructions. Hamilton specifically calls for four-way stretch fabric with 40–65% stretch and lists lining and gusset options. For other patterns, consult the packet’s fabric guidance and notions list. Match the fabric’s stretch to the pattern instructions before cutting.
Do you want bottoms only or a coordinated set?
Choose a pattern with additional pieces if you want a matching top or cover-up. M8502 includes a bikini top and mock-wrap skirt, while S8932 lists tops, shorts, wraps, skirts, and a coat. M8329 includes tops and a one-piece view. If the bottom cut is your main priority, compare the explicitly stated rise and leg details first.
