It's not uncommon in the less-than-scientific world of fashion to be superstitious, and Alessandro Dell'Acqua is very superstitious. So much so that he looked to numerology to christen his No. 21 label through a rearrangement of his birthdate. The resulting lucky number, if his Spring men's collection was any indication, is working.

Twenty-one also happens to be the number of looks Dell'Acqua presents each men's season (a little more in his women's shows). It's over in a flash, so he ushers in the collection again right away, shooing one set of attendees to make room for the next. Two shows, one collection. Seeing a pattern?

Speaking of patterns, there was no shortage of those. Pulled from the gingham and flora families, checks and green leaves were mixed, matched, and manipulated in a patchwork jumble just geeky enough to be interesting without crossing over into self-conscious, look-at-me territory. Baggy T-shirts were emblazoned with graphic squares and logo-embossed, and nearly every look was shown layered with sheer undershirts in ruddy hues. An optical lurking-tiger image in pony was a wallop in an already punchy lineup. The clash of leitmotifs was a much-needed shot in the arm for a city not particularly known for taking risks. Maybe there's something to this numerology thing after all.
