Clothing Size Calculator

This covers the garments sized off the upper body: dress shirts, jackets and suits, and the letter sizes that tops are sold in. Give a neck and sleeve and it returns the collar and sleeve tag, the letter size and the European collar in centimetres; give a chest and a height and it returns the jacket size with its length code, the UK and EU numbers and the trouser waist a matching suit comes with. A third action reads a chest or bust straight onto the letter chart and shows how far you sit from the sizes either side. Dresses, trousers, bras and shoes have their own pages, and letter sizing is the least standardised part of all of this, so a measurement in inches is always worth more than a letter.
