Now, if you just got your first job on a ship, I don't recommend that you buy a lot of nautical-style clothes with epaulets, etc. But you may have some specs for clothes that are hard to find.
When I got a job onboard the Sea Goddess I had to get white dockers. Not easy to find in Norway during the winter.

The shops below are in Ft Lauderdale, and they cater to yacht and ship crews. You just might find the hard-to-find items there:

Antibes Yachtwear : 1532 Cordova Rd., Ft. Lauderdale
Antibes Yachtwear - Uniforms and Logo Apparel

Sebago Docksides (deck shoes): 1376 S.E. 17th st.
Big Blue Yachtwear : 1344 S.E. 17th St. Ft Lauderdale.
