If clients in a hot or humid market want protection at the underarm, brief sewn-in underarm shields (sweat guards) as their own line — sewn in or removable, size, material and colour — and ask on the order thread what is feasible for your style before the sample, because a shield sits in the armhole lining and is fixed when the sample is sealed; this page makes no claim about which shields are stocked. Wikipedia's underarm liners entry explains that liners — also called underarm shields, sweat guards and dress shields — absorb moisture at the underarm, notes that sweat contains substances that can stain yellow or fade dyes, and describes reusable liners made of double-ply cotton on one side with a nylon or vinyl barrier on the other.

Which underarm shield details go on the jacket brief?
- Type: Sewn in, or removable — Ask what is feasible for your style
- Size and shape: As on a reference garment, or ask for a proposal — Measured across the armhole seam
- Material: Absorbent face towards the body — State any fibre preference
- Colour: Matching the lining — Checked on the sample
- Scope: Per client (MTM) or per style (bulk) — Written on the brief
- Lining: A breathable lining helps as well — See lining fibre for humid markets
When do underarm shields make sense?
- Clients who wear the jacket all day in heat, or who perspire heavily.
- Light-coloured linings, where marks show first.
- They add to, and do not replace, a breathable lining and the right construction; see warm-climate construction.
Where does this sit on the clock?
Sample 7–14 days and production 14–21 days after measurements, cloth and construction are locked. Production days are not delivery days. Shields are part of construction, so they belong in the brief; on bulk from 50 per style the sealed sample shows them for the whole run.
"Tell us before the sample whether you want underarm shields, sewn in or removable, and in which colour; the sealed sample shows the choice. MTM from 1 · bulk from 50 per style · WhatsApp +65 8013 8838."

FAQ
What are underarm sweat shields in a suit jacket?
Absorbent pieces set at the underarm, inside the lining, to take moisture before it reaches the jacket. They are also called sweat guards or dress shields.
Can sweat stain a suit jacket lining?
