From EvielaLuveDIY:
The Xo bra is a beautifully simple silhouette with style lines horizontally across the cups. You can make the most of these style lines by using contrast fabric, sheer stretch mesh, lace etc. It's really easy to make this pattern fun and unique! It's a simple sew and a great place to start for a beginner bra maker. This pattern is drafted for a C cup but it is a simple pattern adjustment for different cup sizes. I have a tutorial for this on my YouTube channel for a similar bra (see links below).
Skill Level:
Intermediate. If you are new to sewing bras don't let 'intermediate' put you off! There are sooo many photos and step by step instructions which simplifies the process of sewing this pattern. Skills you may find useful (or will learn on the job) are sewing with various lingerie elastics such as FOE and picot and sewing with stretch fabrics.
