306 Mott Street
There is a big difference between someone who can do alterations and a true tailor who can pattern a dress or construct a suit. Ramón Diaz has been expertly fixing clothing for fashion cognoscenti since 1969. Don't be shy about unusual requests. For Halloween, he made a full papal vestment for a mere $90. Hemming pants: $11.
1255 Second Avenue, near 65th Street
Have a favorite jacket that's seen better days? Madame Paulette's tailors will duplicate the pattern and fashion an exact replica. A unique finish on a sleeve that needs to be shortened is no problem they'll take it up from the shoulder. And hemming a wedding gown's cathedral train is as common for them as altering the length of jeans. Hemming pants: $15.
Meurice Garment Care
245 East 57th Street
Mercedes, the tailor at Meurice, hates to say no. A bride recently brought in her great-grandmother's wedding dress, and Mercedes was able to restore the bodice, duplicate the beading, and re-create the rest of the garment. As for that rip in your suede jacket when you get it back, you won't be able to find the repaired spot. Hemming pants: $15.
18 w. 23rd Street, at Fifth Avenue, 4th floor.
Helmut Lang, Costume National, and other design houses send clothing regularly to veteran Wilfred's Tailor. He'll be happy to work with your sketches. Hemming pants is just $10.
