The sides and back are open which gives you the illusion this is a one piece bathing suit. However, in the front the stomach is modestly covered up. This style features a v-cut in the the front with a rounded back neckline. It also has a belt design feature just under the bust for style and added support.

What other sewists are saying: This is the latest free swimsuit pattern from Mood Fabrics but based on the comments it has received a warm reception. Sewists like the design and appreciate it not having bulky bust cups.

Description: The Sherwood Swimsuit from Mood Fabrics is a one-piece bathing suit with a subtle peekaboo design on the right ribcage.  It features a side-tie design element down the right side of the swimsuit giving it a high-end look especially with the grommet finish. The one shoulder design and the full coverage bottom provide a flattering silhouette for any body type. 

What other sewists are saying: The Sherwood Swimsuit pattern has received great feedback from sewists online.  They love that even though it is strongly encouraged to use a serger you can still sew this swimsuit with your trusty zigzag stitch setting on your regular sewing machine.  You can even use the mock overlock stitch that is featured on some sewing machines. A couple of sewists mentioned they made this swimsuit without the grommets and had good results. Just remember to account for your plackets if you go this route as suggested by the designer.

Description: No serger needed for this pattern! This is a cute, quick sewing pattern great for first time swimwear sewists.  The Phoenix from Mood Fabrics is a one-piece full bottom coverage swimsuit with a cute and stylish long ruffle over the bust adding a bit of elegance to your beach vacation. The most complex this sewing pattern will get is a French seam which is great for beginner sewists to learn. The Phoenix swimsuit pattern translates well into a form-fitting body suit as well.

What other sewists are saying: Sewists are loving the simplicity yet elegance of this swimsuit pattern. They love that they don’t need to own an expensive serger sewing machine to create a beautiful and functional swimsuit.  They also like that it is versatile enough to add in a shelf bra for extra support.
