The actual rule is:
307. Dress Regulations
(a) Members of the Society shooting and officiating at tournaments granted National or
World Record Status by GNAS are required to wear the accepted dress of the society
as detailed below.
(b) Ladies are required to wear a dress, skirt, trousers or shorts with a suitable top which is
not strapless, nor beachwear.
(c) Gentlemen are required to wear trousers or shorts with long or short sleeved shirts.
(d) Footwear must be worn at all times during the tournament.
(e) Sweaters, cardigans, blazers and other outer clothing may be worn provided that they
comply with the requirements below.
(i) The recognised dress of the Society is plain dark green or white. There is no
objection to wearing green and white garments together. Minor piping on the
garments is also permitted. The name and/or emblem of an archer’s club, county,
regional or national association or society may be worn on the recognised dress of
the Society.
(ii) A club, county or region may register alternative shooting colours with the Society
as detailed below. For members of such a club, county or region to shoot at a
record status tournament in their shooting colours, these colours must be
registered with the Society at least one month before the end of the previous
affiliation year. The process for registration of shooting colours is included in the
Shooting Administrative Procedures.
(iii) Shooting colours shall consist of skirt, trousers or shorts in plain dark green or
white, as defined above, and an upper garment of no more than four colours. The
upper garment shall display the club, county or regional badge, name or logo. This
name or logo may be embroidered onto the clothing or attached after manufacture
and can include badges pinned to the garment. The colours of the badge may
exceed four.
(iv) Olive Drab and camouflage patterns are not acceptable as shooting colours.
(v) Members of the Society who are officiating at a National or World Record Status
tournament shall not wear club, county or regional shooting colours if they are
acting in the capacity of Chairman of Judges, Judge or Director of Shooting.
(vi) At National tournaments where there is a Home Nations’ team competition
incorporated into the event, nominated members of the teams will be permitted to
wear the dress of their Home Nation (i.e. England, Northern Ireland, Scotland or
Wales), as approved by their organisation, throughout that tournament.
(vii) Archers who are members of other national associations or societies that are
affiliated to FITA may wear the shooting uniform of their home country.
(viii) A member of the Society who has represented Great Britain as an archer at an
international tournament may wear their international shooting uniform, as an
alternative to the accepted dress detailed above, for the remainder of that season
and the following one.
(ix) An archer who affiliates directly to GNAS may nominate one club whose shooting
colours they may wear. In this case they will be required to show evidence from
the club (preferably a letter from the Club Secretary) confirming that they are a
member of that club and the club has granted them permission to compete in
those shooting colours.
(f) If the judge in charge of the tournament declares the weather inclement, waterproof
clothing worn only during this time is not subject to these regulations, either for those
members of the Society competing or officiating. However, waterproofs in the
recognised dress of the Society or the registered shooting colours are recommended.
(g) Advertising material must not be carried or worn except in conformity with FITA rules.
(h) Any archer not conforming to the above regulations shall be required, by the Judge and
Tournament Organiser, to leave the shooting line and will not be permitted to take part
in the competition.
