Hello! We are starting to experience warmer weather and in anticipation of getting some pool/beach time I am getting ready to make some swim pieces. Since I am researching and looking into swim patterns anyway, I thought I would compile my swim pattern findings into a list or two.

The Bikini Patterns list is divided into three sections: Bikini Top Patterns, Bikini Bottom Patterns and Bikini Set (Top + Bottom) Patterns. This list includes 8 Bikini Top Patterns, 8 Bikini Bottom Patterns, and 14 Bikini Set Patterns. All patterns listed here are in PDF format.

If you are just dipping your toes in swimwear sewing, I hope this list is a good starting point for you! If you are looking for a specific swim style or silhouette, I also hope this list helps you narrow down your search.

Note: This is by no means a comprehensive list of all the existing bikini swim patterns out there. Consider this list a starting point for exploring bikini pattern options available currently. If you have a favorite bikini swim pattern to recommend that’s not on the list, feel free to drop a comment below!
