Choose custom undershirts for your team
Identify whether officers wear a button-front shirt, a polo or another approved outer garment. Check the neckline and sleeve openings on that actual piece before choosing the undershirt style. A base layer that suits one shirt can show at the neck or cuff of another. Record the intended combination in the purchasing brief. This keeps the order focused on compatibility rather than choosing an undershirt as an isolated casual garment with no uniform context.
Agree on Neckline Visibility Across the Team
Decide whether the dress code allows the undershirt to show when the outer collar opens. Compare the proposed neckline with the outer garment in both standing and seated positions. Check coverage without pulling the shirt into an unnatural position for the fitting. Include any colour rule in the specification. A clear decision helps purchasing avoid a mixed appearance across staff and prevents wearers from choosing different neck shapes after the full uniform order arrives.
Review Sleeve Coverage Under Short Sleeve Shirts
Try the base-layer sample under the actual short sleeve uniform where relevant. Ask wearers to raise their arms and reach forward, then inspect whether the undershirt sleeve shows. A static fitting can miss that change. Record the sleeve relationship separately from chest fit, because moving up or down a body size may not solve it. Keep the chosen combination as a reference for later staff additions so replacement pieces work with the same outer shirt.
Check Body Length Through Normal Shift Movement
Ask wearers to bend, sit and reach with the full uniform tucked as the role requires. Check whether the base layer stays in a comfortable position or collects excess fabric at the waist. Compare the proposed length with different torso proportions. A very long layer can feel bulky beneath fitted trousers, while a short one may move out of place. Describe the actual problem in the sample notes so the fitting decision addresses the right measurement.
Compare Fabric Feel With the Intended Outerwear
Request the proposed composition, weight and care instructions. Review how the fabric feels directly against the skin and how it sits beneath the outer shirt. Treat moisture control, odour control and other functional claims as features that need confirmation and evidence where relevant. Avoid promising a health or protective benefit from a base-layer name. Let the intended work conditions and the sample review guide the specification you ask purchasing to approve.
Inspect Seams and Contact Areas During Fitting
Ask wearers to comment on shoulder seams, side seams and any label or decoration that touches the skin. Trial the sample beneath the layers staff normally use, since pressure can change when the outfit closes. Record any rubbing or bulk rather than accepting a general statement that the garment feels comfortable. If your team needs a particular label arrangement, include that request in the brief and ask for confirmation before assuming the proposed style provides it.
Build a Practical Issue Quantity Per Officer
Work out how many base layers each employee needs between laundry cycles. Keep that allocation decision separate from the number of officers in the contract. Prepare quantities by size and distinguish initial issue from spare stock. Ask wearers to compare measurements with the proposed chart instead of ordering automatically from their outer-shirt label. A base layer can use a different fit, and the purchasing schedule should reflect that difference before you request final pricing.
Review Appearance After the Intended Care Routine
Follow the sample care instructions and inspect the neckline, sleeve length and body fit again. Check the garment beneath the outer uniform after washing rather than judging it alone. Note any conflict with staff laundry arrangements before approval. Do not infer a fixed service life or shrinkage result from an untested fabric claim. Keep the actual care guidance and sample observations with the order so later purchasing decisions follow an agreed reference.
Keep Decoration Appropriate for a Base Layer
Decide whether the garment needs visible branding at all. If you request a logo or wearer identification, review its position against skin contact and outer-shirt visibility. Small internal identification may raise different comfort questions from a chest mark. Supply the artwork and ask for the proposed application method. Confirm that the final arrangement suits the purpose of the layer rather than copying the decoration plan from a jacket or another garment with a different role.
Request Pricing for the Approved Layering Combination
Send Masswear Uniform the outer-shirt reference, desired neckline, colour, size mix and quantity allocation. Add any identification request, destination and required date. Ask for the proposed fabric and sample review arrangements in the quote. Keep the approved base-layer specification alongside the outer-shirt record so purchasing can maintain the combination when uniforms change. Recheck compatibility whenever you introduce a different collar, sleeve length or fit into the main security uniform.
