Want to look sinfully good without trying? Work what your mama gave you with Le Fabuleux Marcel de Bruxelles, the ne plus ultra of tank tops (for zee most sensual part of zee body). Marcel is what the Belgians call a singlet (beaucoup mieux que “wife beater,” non?) — the uniform of truckers, miners, and modish street urchins like yourselves, messieurs-dames. The shirts wrap your body like Christo and Jeanne-Claude; the cuts and styles are shapely in the right places. Le Pablo’s skinny stripes transport you to the côte, Kir in hand. Le Haut has a Belgian waffle recipe typed across it in French. Le Clochard has a deep cut to show some skin. (You might wake up wearing it with no recollection of the night before.) But Le Fabuleux is the Marcel of all Marcels. It won’t make you a better person. But it claims to make you a hotter one. Ze devil ees een zee details. Available at Mick Margo, 19 Commerce Street, between Seventh Avenue South and Bedford Street (212-463-0515).
