Straight answers on how the Delphine Knickers in black modal jersey fit, what to expect from the full brief cut, and how to choose your size.
Quick answer
Choose your usual size in the Delphine Knickers. The modal jersey is soft and stretchy, and the full brief cut with gentle elastic is designed to sit comfortably rather than compress, so most people do not need to size up.
What the full brief cut means for fit
The Delphine is a retro-inspired full brief with a gentle flounce along the leg line. That shape gives more coverage through the seat and front than a bikini or high-leg style, so the fit feels secure without relying on tight elastic. If you usually find full-coverage briefs too warm or bulky, this cut may feel like more fabric than you prefer. If you like a brief that stays in place, the extra coverage is the main reason to choose it.
How the modal jersey affects sizing
Modal jersey knitted in Melbourne gives the knickers a soft, stretchy handfeel. Because the fabric moves with you, the fit is more forgiving than a rigid woven brief. The gentle elastic trim and babylocked edges are there to keep the edges flat without digging in. If you are between sizes, the stretch usually makes the smaller size workable, but the full brief shape means the larger size may feel roomier rather than loose.
When to size up or down
Size up if you prefer a relaxed, almost weightless feel through the waist and leg, or if you are ordering for a body shape that often needs more room in the hip. Size down only if you want a closer fit and you are already at the lower end of your usual size range. There is no drawstring or adjustable waist, so the elastic is the only give in the fit. The optional bow is decorative and does not change the sizing.
Delphine Knickers fit questions
- Should I size up in the Delphine Knickers?
- Not usually. The modal jersey is stretchy and the full brief cut is generous. Size up only if you want a looser, more relaxed fit or you are at the top of your usual size range.
- How should modal knickers fit?
- They should feel snug but not tight, with the elastic sitting flat against the skin and no digging at the waist or legs. The fabric will move with you, so you should be able to bend and sit without the brief riding up.
- Will the full brief cut show under clothes?
- The full brief covers more of the seat, so it can create a visible line under very tight or thin fabrics. The gentle flounce along the leg line helps reduce leg-edge dig, but if you need a completely invisible finish under close-fitting clothes, a different cut may suit you better.
- Can I choose the bow colour?
- Yes, the Delphine Knickers come with an optional bow, and you can select the bow colour when ordering. The bow is decorative and does not affect the fit.
