Underwear/UnderpantsCSSBuy Spreadsheet
Underwear is the most underrated bulk-buy category in the CSSBuy Spreadsheet. Because the items are small and lightweight, adding 5–10 pairs to an order barely changes shipping costs. This gateway page covers fabric choices, waistband construction, and how to read the sizing which is often based on Asian standards. Before you open the full Underwear/Underpants catalog, use the checklist below to avoid the common waistband stretch and seam issues.

- Buying 100% cotton without any stretch; it loses shape quickly.
- Ignoring the rise height; low-rise cuts can feel uncomfortable.
- Not checking the inseam on boxer briefs; too short causes ride-up.
Style Guidance

- Trunks work best under slim-fit pants.
- Avoid loud prints if you wear light-colored pants; they show through.
- Dark neutrals and heathers are the most practical daily colors.
QC Checklist
- Waistband rebounds after stretch.
- Seams are flat and not raised on the inner thigh.
- Fabric is soft and not scratchy.
- Leg opening is elastic enough to stay in place without binding.

Size & Fit Advice
Underwear sizing is almost always based on Asian measurements. Convert your waist size from inches to centimeters and add 2–3cm for comfort. If you are between sizes, size up. The waistband should sit at your natural waist without rolling or digging. Check the leg opening measurement: 18–20cm is standard for boxer briefs.
