Quick answer
For the Jane Onepiece, start with your bust and hip measurements, then check the size chart. The high-cut legs and deep back mean the fit is forgiving, but the hidden seams hug curves closely.
Why size matters for the Jane Onepiece
The Jane Onepiece is designed with a high leg cut and a deep back, giving it a sleek, 80s-inspired silhouette. The hidden seams are meant to follow your curves, so getting the right size ensures the piece stays put and flatters without digging in.
Unlike a classic one piece, the Jane has less coverage on the sides and back, which means the waist and hip fit are more critical. If you are between sizes, consider whether you prefer a snugger hold on the legs or a little more ease through the torso.
Trade-offs to consider
The Jane is made from sustainable materials in Berlin, which means the fabric has a firm, supportive feel. It does not stretch out as much as conventional swimwear, so sizing up is rarely needed unless you are between two very different measurements.
The high-cut legs can feel revealing if you are used to fuller coverage bottoms. If that is a concern, you might prefer a more modest one piece, but for those who like a leg-lengthening look, the Jane delivers.
Decision rules for choosing your Jane Onepiece size
- Measure your bust and hips: Use a soft tape measure around the fullest part of your bust and the widest part of your hips. Compare both to the size chart. The Jane has no cups, so bust measurement is for overall fit, not support.
- Check your torso length: If you have a long torso (over 60 cm from shoulder to crotch), the Jane may feel short in the body. Size up if you are between sizes and have a long torso, but expect a slightly looser fit through the legs. Consider torso length as a key factor, not just bust and hip.
- Decide on leg coverage preference: The high leg cut means the leg opening sits high on the hip. If you prefer more coverage on the thigh, size up for a lower cut. If you want the full 80s look, choose your regular size based on hips.
- Use the return policy if unsure: If you are between two sizes, order both and return the one that does not fit. The Jane is a precise fit piece, and the sustainable fabric does not give much stretch. Order two sizes if you are between measurements.
