Koh Samed Island
Four to five hours away by bus and ferry from Bangkok, this island south-east of Bangkok is quite popular among the Thais in the region, but it's not overcrowded. Only few foreign tourists have discovered Koh Samed, but as there is no airport and as there are hardly any tour-package resort hotels, mass foreign tourism has spared Ko Samed so far.
It is cheap to get there and basic bungalows can be found for very reasonable rates. The island has only a few inhabitants; there is no settlement of any significant size on Koh Samed.
There is one small asphalted road and a few other roads that are often unpassable with normal cars. One tiny post office, a few very small supermarkets, some restaurants and bars/pubs provide basic services to keep visitors on the island for some time.
The beaches are beautiful and the sea is usually clear, mild and warm. Koh Samed is no party-island but a relaxing and slow-going romantic place, where especially couples can spend an unforgettable time.
Traditional Thai swimwear is made of silky soft cotton.
Modern fibres like Nylon and polyester are also available.

I'm in Ko Samed, Thailand where it is customary for people to swim in clothes. Most of the action is around sunrise and sunset. Around midday you see see only a few tourists on the otherwise empty beach, frying their skins.
If you like to see lots of people in wet T-shirts (long or short sleeve) and shorts or pants of all length, including jeans, than this is the place for you. Don't miss the wet beach ball games at 6am. It's a fun way to start you day.
