Care and clinical uniforms put small text (a first name and job role under the organisation's logo) onto lightweight polyester-cotton that puckers if the stitching is too heavy.
We open up the lettering so names read at badge size and keep the logo as light as coverage allows. NHS England's uniforms and workwear guidance for NHS employers refers to a 10-minute wash at 60°C, so tie-offs are locked to hold through that repeated washing without stiffening the tunic.
For name and role sizing in more depth, see small text digitising; for chest logo widths, left chest sizing.
Rippling around a tunic logo usually means density set for a polo. Tunics need a lighter build of the same logo.
