Greetings, Spiketickles,
... Victoria's Secret ... just the sound of it ... :) ...
... do not know of any "stand alone" VS shops in Bangkok, but a few lingerie purveyors can be found in the "World Trade Center" area near the Four Seasons ...
...am currently "seeing" a lovely Bangkok woman, and she insists that I purchase VS (and La Perla) lingerie for her before leaving for Thailand, so that may be a clue that VS is not that prevalent in BKK (or perhaps, someone is being ... used ... ) ;) ...
... you will find "originals" and "knock-offs" of all the "top" brands in Bangkok. If nothing else, spend a bit at a Jim Thompson store. Beautiful Thai silk products, and the shop assistants... :)
You will have a lovely time,
macintosh (Robert)
