Removable pads slip into pockets inside the bra, so customers can take them out, change them or wash them separately. They make one bra suit more people and are cheaper to produce, but they can fold, shift, look uneven and get lost. Sewn-in or moulded cups are fixed in place, so the shape stays consistent and there is nothing to lose, but customers cannot adjust or remove them and the bra may take longer to dry.

Making removable pads work

Many complaints come from the pocket, not the pad. If the pocket opening is large and loose, the pad moves. A smaller opening, a pocket shaped to the pad, and a pad that fills the pocket properly reduce shifting. Pad material and edge shape also matter: thinner edges and a slightly stiffer foam fold less. Ask for pads matched to each size, not one pad for all sizes.

Sewn-in cups

Moulded cups give a smooth look and are common on medium and higher support styles. Check that the cup is sized to each bra size and sits evenly, and that the stitching holding it is flat and comfortable. Drying time is longer, so check how customers will dry them.

Washing

Wash samples with a named procedure such as ISO 6330 at your label conditions, including tumble drying if allowed. Check pad shape, folding, lumps, shifting and any change in the moulded cup. Recommend a laundry bag on the care label if testing shows it helps.

The band still does the work

Pads and cups shape and cover; support mainly comes from the band, the fabric and the straps. Test band elastic with a method such as ASTM D4964, new and washed. If you make moisture-management claims, test with suitable methods such as the AATCC moisture management methods.

What to specify

Give the pad or cup material, thickness, shape and size per bra size, the pocket dimensions and opening, attachment method for sewn-in cups, and the wash test. Approve washed samples worn by testers across sizes.

Decide by support level and customer feedback, and consider offering both in different styles. Whichever option you choose, keep an approved washed sample in each size as the reference for bulk and reorders, and record the pad supplier and foam specification so a later substitution is noticed.
