.....does anyone know if sailors have uniformed sleeveless shirts underneath their smart white uniforms and are they allowed to work without their uniforms?
We do wear the short sleeve shirt under the white tunic (its not sleeveles

). However, depending on the heat conditions in summer time, the uniform dress code can be varied as following:

tropical day service uniform

tropical evening service uniform

extreme heat service uniform
All three of them are wore in non-essential and non-key service operation positions. For a key position service, such as guard or patrol duty we wear:

and here is the formal uniform

There is also a blue uniform that is wore on office and electronic equipment operations positions, or just for a dirty job...:

Winter

Summer
Btw, we only wear the whites in summer time... we wear the blue uniform in the winter.

Navy dress code is a proud tradition, but its also a big headache

Hope the above gives you some further inspiration for your customs, cheng
