Intimate apparel engineering notes
Notes for people who brand, import and sell intimate apparel: how to read a spec sheet, which construction details decide fit, why panels fail, which certificates each market asks for, and how a program moves from sample to container.
- What is a balconette bra? Cut, coverage and fitA balconette bra covers half the breast with a horizontal neckline and wider straps. The construction, how it differs and what a buyer should specify.
- Bra types explained: from balconette to braletteBalconette, demi, plunge, strapless, push-up, wireless, bralette and sports bras compared by coverage, support structure and what a buyer should specify.
- Strapless bra fit: staying power without wiresHow a strapless bra holds without straps: silicone grip tape, band engineering and cup structure. Fit checks to run and what to specify for production.
- Push-up bra padding: levels and constructionPush-up padding runs in graduated levels from light to level three. How the foam is layered, removable pads, molding lines and what to check before ordering.
- Wireless vs underwired bra: comfort meets supportWireless bras move support into band, fabric and pattern; underwired bras use hardware along the fold. Where each construction fits a range and what to compare.
- Bralettes: construction, fabrics and sizingBralettes drop wire and padding for fabric-led construction. Triangle and sports cuts, lace and modal fabrics, XS-2XL sizing and how to plan a program.
- Sports bra impact levels: low, medium and highLow, medium and high describe the design load a sports bra is built for. Compression vs encapsulation, four-way stretch fabrics, testing items and program notes.
- Sticky bras: adhesive design and careA sticky bra replaces bands and straps with a skin-contact adhesive front. How the cup and adhesive are built, wear limits, care routines and program notes.
- Nursing bra construction: access and comfortNursing bras add one function to everyday support: single-hand cup access. Drop-cup clips, crossover builds, stretch panels, testing items and program notes.
- Minimizer bras: design goals and fitMinimizer bras are engineered for a lower profile under clothing through fuller cups, wider wires and side support. Design goals, component differences and fit.
- How to choose a panty style: coverage and riseHow panty styles differ by rise, coverage and fabric, with construction notes across briefs, bikinis, boyshorts, thongs and period underwear lines.
- Brief vs bikini panties: cut and coverageBriefs and bikinis differ in rise, side width and rear coverage. Cut facts, fabric options and range planning points before ordering either style.
- Boyshorts: full-coverage constructionBoyshorts borrow a menswear brief silhouette: mid rise, full rear coverage and a straight leg opening. Pattern, fabric and sizing notes for buyers.
- Thong construction: seams and comfortA thong is a front panel, narrow sides and a T-shaped rear. Construction details - seams, gusset lining and elastics - that decide comfort and quality.
- Period panties: layers and absorbencyPeriod panties use a four-layer absorbent structure in the gusset instead of disposable inserts. Layers, flow grades, testing points and typical MOQ.
- Seamless panties: bonding and knittingSeamless panties get their edge-free finish through circular knitting and bonded construction. How the two routes differ and what buyers should specify.

- Panty sizing: waist, hip and inseamPanty sizing: waist and hip measurement, letter-to-numeric mapping, rise and leg opening, stretch tolerance and how size ratios are planned for production runs.
- Signs of a good fit: band, cup, strapBra fit checks in fitter order: level snug band, cups that contain without gaping, straps that carry little, and the movement tests that confirm all three.
- Cup volume and sister sizes explainedCup volume scales with the band, which is why sister sizes exist. How the diagonal works, where the equivalence breaks and how grading uses it.
- International bra size conversion guideBand and letter conversion across US, UK, EU, French and Australian charts, why tables disagree, and the protocol a desk uses to serve one range to several markets.
- Band tightness: two-finger rule and beyondHow tight a bra band should be: the two-finger test applied properly, hook rows as built-in adjustment, elastic recovery, and the testing that keeps bands anchoring.
- Why bra sizing varies across brandsBra labels are self-declared: grading bases, elastic lots and style intent all move sizing. Where the variance comes from and how a brand controls it.
