The traditional dress of the Irish consists of a large yellow tunic called a léine, a type of cloak called a brat and a short jacket called an ionar. For women we have the gúna as well as the léine and the brat. The evidence for this is water-tight and conclusive. Items wich are not nationwide traditional Irish attire include the kilt, Aran jumpers, Kinsale Cloak and Irish dancing costumes. This list contains items that are either bogus (kilt), introduced (Aran jumpers and Kinsale Cloaks0 or just ridiculous late 20th century inventions (Irish dancing costumes). Irish traditional attire almost died out completely in the early to mid 1600s but survived longer in Connemara and to the present day by a small number of enthusiasts. Traditional Irish clothing is the traditional attire which would have been worn historically by Irish people in Ireland. During the 16th-century Tudor conquest of Ireland, the Dublin Castle administration prohibited many of Ireland’s clothing traditions.^[1]

Aran jumpers were invented in the late 19th century. Irish Tweed is a woven fabric incorporating multi-coloured neps - scraps of wool said originally to have been swept from the floor under the looms at the end of the day, and incorporated into the next day's weaving. In the past, much weaving was done in the home, with the fabric being delivered to a broker. Today, a few mills exist around Ireland which re-create this tweed in the traditional manner. Donegal is the heartland of Irish tweed and Donegal tweed is better known than other Irish tweeds. Beady pockets are a component of traditional Irish Traveller (Shelta: Mincéirí) attire. They are flat, pocket-sized pouches characterised by elaborate embroidery and beadwork.^[2]

Cloaks called brait (singular: brat), on the other hand, would signify wealth if they were made from several different colors. In fact, sumptuary portion of the brehon law decreed that slaves could only wear cloaks with one color, while freemen could wear four and kings wore several different colors.^{[dubious – discuss]} Beneath these brait, they wore léinte (singular: léine), long woollen or linen tunics that extended to the ground but were gathered into pleats and belted so that they fell to the knees (the excess material was allowed to hang down at the waist and cover the belt, as can be seen in the Dutch painting illustration). The léine was very wide at the bottom and narrow on top. Likewise, the léine's sleeves were narrow at the upper arms but widened greatly at the elbows. The sleeves were open to allow the lower arm to emerge, but hung down behind the elbow to the knee or sometimes as far as the ground in more ceremonial garb. Léinte were most often saffron-yellow (léine croich, 'saffron shirt'), but were also found in other solid colours (red, brown, green, black, etc.), or occasionally striped. The léine was worn throughout Gaelic culture, including in western Scotland, up until the late 16th century. In Ireland, traditional Gaelic dress, including the léine, was banned by the Dublin Castle administration.

Another garment, known as an inar, was a jacket, pleated at either beneath the breast, or at the waist, with split sleeves. Woodcarvings seem to indicate that inar were richly decorated, possibly through embroidery. In winter, a cota mór was added beneath the brat; this was a greatcoat made of thick wool, with a small standup collar and sleeves that unbuttoned below the elbow to allow the long sleeves of the léine to come through. Less is known of the early apparel of the Irish women and children. Like men, women's clothing was mostly derived from wool. It is likely that the earliest female inhabitants of Ireland also donned léinte which looked similar (if not identical) to those of their male counterparts. By the fifteenth century, women were wearing long dresses made from wool cloth, often decorated with ribbons and other accessories. These dresses were created and worn in direct imitation of those worn in England.
