Set In Pad

Definition and Overview

A set in pad is a shoulder pad for set-in sleeves, sewn into the armhole of the body. It has a shape that gradually widens from the shoulder point toward the armhole side, supplementing thickness and roundness around the shoulder line and creating a three-dimensional shoulder area.

It is sometimes simply called a shoulder pad, but the defining feature of a set in pad is that its shape matches the sleeve attachment line of a set-in sleeve. It is used to follow the sleeve position and shoulder slope, improving the appearance of the outer fabric.

Area of Use and Role

It is mainly used at the shoulder point of jackets, coats, dresses, and similar garments, and is placed between the outer fabric and lining, or between the outer fabric and facing. It also helps refine the shoulder outline and makes dents at the sleeve attachment and impressions from seam allowances less noticeable.

Depending on the thickness and firmness, you can adjust the impression from a structured, crisp shoulder to a natural, soft shoulder. It is used not only to emphasize shoulder width, but also to maintain shoulder shape in thin or soft outer fabrics.

Materials and Types

The core materials include nonwoven fabric, wadding-like fibers, and foam, and many are wrapped with nonwoven fabric or knit fabric on the surface. Lightness, resilience, ease of sewing, and suitability for washing or dry cleaning vary depending on the material composition.

Shapes vary in shoulder-point thickness, projection toward the armhole side, and front-to-back thickness balance. Choose according to the design and fabric thickness from thin, natural types, thick types, and types that emphasize the shoulder point.

• When the outer fabric is thin, consider a thin, smooth type that makes the outline and the show-through or impression of the core less noticeable.
• For heavy garments, check the resilience and shape stability needed to keep the shoulder form from being overwhelmed by the weight of the outer fabric.
• Because they are used as a left-right pair, be careful not to mix up the thickness, shape, or front-back orientation.

Main Applications

In tailored jackets and suits, they are used to refine the shoulder line and make the sleeve attachment look neat. They are also used in coats, uniforms, and formalwear, adjusting shoulder presence and neatness according to the purpose.

In dresses and design-focused dresses, they may be used as auxiliary materials to create the shoulder-point form. On the other hand, in garments that emphasize drape and softness, omitting the pad or using an extremely thin one is also an option.

Selection and Sewing Notes

When selecting, check the shoulder width, shoulder slope, armhole shape, outer fabric thickness and stretch, and whether there is a lining. If the pad is too large, it tends to protrude toward the armhole side; if too small, it will not support the shoulder point sufficiently and it becomes difficult to achieve the intended silhouette.

During sewing, align the center position and front-back orientation of the pad, and lightly secure it to the shoulder seam and armhole seam allowances. If the outer fabric is pulled when sewing the pad on, puckering or unevenness may appear on the outside, so finish while checking the amount of ease.

A raglan shoulder pad is a shoulder pad corresponding to the seam line of a raglan sleeve, so the suitable sleeve structure differs from that of a set in pad. A for dropped shoulderline pad refers to a decorative pad with the surface wrapped in the same fabric or similar material, and the intended use and approach to appearance are different.

Frequently Asked Questions

Can set in pads and raglan shoulder pads be used interchangeably?

As a rule, use the type that matches the sleeve structure. Set in pads are for set-in sleeves, in which the sleeve is attached to the body armhole, while raglan shoulder pads are designed to follow the raglan line that runs from the neck opening to the underarm. If used interchangeably, they will not blend into the sleeve attachment line, which can cause impressions and shape distortion.

Which way should a set in pad be attached?

Because front-back and left-right orientations vary by product, check the label and specification sheet before placement. In general, align the shoulder point position and the curve toward the armhole side, and attach symmetrically on both sides. After basting, check the shoulder seam, sleeve attachment, and shoulder-point tension from the outside before final stitching for stability.

Can set in pads be used in washable garments?

Yes, but it is necessary to confirm the garment's washing method and the pad's wash resistance in advance. Since the core material may crush, shift, or change shape after washing, it is important for products intended for home laundering to conduct washing tests with the outer fabric and lining combination.
