The key to good shooting is being relaxed and comfortable. Archery is an informal sport and most definitely not a fashion show! Clothing should be suitable for you to shoot in and appropriate to the weather conditions when outside.
Close fitting tops such as a tee-shirt, polo shirt or similar is ideal. Avoid anything baggy as it can become tangled in the string, spoiling your score and the clothing! No ties (remember, relaxed and informal!), chains or necklaces visible outside your clothing and no open toed shoes.
Long Hair should be tied back to prevent interfering with the bow string.
