Chapter 84:1
Laws of Carrying: Clothing & Jewelry
1. An article which is neither a garment nor jewelry (1) may not be worn
while going out to the public domain or to a "carmelis." Therefore, it is
forbidden to go out with a pin or needle stuck in one's clothes. A male
should be stringent, even regarding a needle without an eye, and even if it
is needed for his clothing. However, since women usually fasten their
ribbons, kerchiefs and similar things with pins, they are permitted to go
out [into the public domain] with pins [attached to their clothing], as
long as it is needed for their clothing (2). This leniency, however, is
granted only for pins and not for needles (with an eye) (3).
FOOTNOTES:
(1) We will see in HY 84:2, that the Rabbis prohibited going out into the
public domain wearing certain types of jewelry, for fear that one might
take the piece of jewelry off to show a friend, and then carry it in her
hands.
(2) For a woman, the pins are considered an extension of her clothing, and
therefore it is not considered carrying.
(3) It is not common to use a needle with an eye to hold parts of one's
clothing together, and therefore it is not considered an extension of one's
clothing (See Shulchan Aruch 303:9 and 301:8, and Mishna Berura)
