This is a vintage set of US Navy SEAL UDT/BUDS combat dive shorts and the reverse able  blue/gold t shirt. These are used in training, diving, ect. The NSW used these from Vietnam era to about the mid/late 1990's. Rare to find now a days. Also included are the dark OD green general purpose shorts also used in swimming, diving, pt, ect. The blue/gold shirt is pretty heavy weight as it's basically two shirts sewn together. It is completely unmarked but is in good used condition. Size I would guess is about a Large. The combat dive trunks are a size 34. They are used and have wear/staining from operational use. The general purpose trunk is a size 32-35 (Medium) and are in almost new condition. I got these about 15 years ago from a ST1 guy who retired about then. The shirts were worn with the gold side out to denote diving status and in the field for extractions and such. Rare to find now a days! These were all part of my personal NSW collection. The last pics show SEALS wearing the shirts and UDT shorts in combat operations late in Vietnam. Mine were just used in the 1990's era.
