Pieces for this answer.
01
Check the held sizes
The product page lists the sizes actually stocked. Compare your bust, waist and hip with the chart, and read the fit notes. One-size pieces rely on stretch and tie adjustments.
02
When to size up
If you are between sizes, take the larger for comfort. Structured costumes, corsets and costumes with zips have less give than stretch lace. Check the return policy before a big event.
03
Dress size is a starting point
A roleplay costume is cut for a look, often closer and with less stretch than everyday clothing. Your dress size is a starting point, not a guarantee. Check the bust, waist and hip measurements against the size list. If the costume has a rigid zip or a structured bodice, the measurement matters more.
04
Measure the body
Measure your bust, underbust, waist and hip. For a bodysuit or a dress, add the torso length. Compare the numbers with the product page. If you are between sizes, take the larger in a structured costume and the closer size in a stretch mesh piece.
05
One size
A one-size costume is a stretch range, not a universal fit. Check the stated range and the model measurements. If you are outside the range, choose a sized style. A one-size piece with ties is more adjustable than a structured one.
06
Plus size
Plus-size availability in roleplay is limited. Check the product page for the exact sizes held; do not assume a style comes in 3XL or 4XL. If you need a specific size, ask before ordering.
07
A quick check
Read the size list, the fabric notes and the included pieces. Check the return policy. If the costume has a zip, a corset or a structured cup, size for the measurement rather than the label. A costume that fits is easier to wear and looks better.
08
Measure, do not guess
Measure your bust, underbust, waist and hip. For a bodysuit or a dress, add the torso length. Compare the numbers with the size list. A dress size is only a starting point; a roleplay costume is cut for a look, often closer and with less stretch.
09
One size and plus size
A one-size costume is a stretch range, not a universal fit. Check the range and the model measurements. Plus-size availability is limited; check the exact size list before ordering. If you need a specific size, ask before buying.
10
A final check
Check the size list, the fabric and the included pieces. Read the return policy. A costume that fits is easier to wear and looks better. Do not rely on ties or straps to create room in a structured piece.
11
A simple sizing plan
Measure your bust, underbust, waist and hip, then check the product size list. If the costume has a rigid zip or a structured cup, size for the measurement rather than the label. If it is stretch mesh, you have more room. Ask before ordering if the size list is unclear. A costume that fits is easier to wear and looks better; do not rely on ties to create room in a structured piece.
12
What to check before ordering
Check the size range, the included pieces and the fabric. Read the return policy. If you are between sizes, take the larger in a structured style. A one-size piece is a stretch range, not a universal fit. A quick message with your measurements can save a return.
