Do your models have to be a particular size or weight?
No! There is no body-fascism here! We have worked with some models who weigh less than 45kg others weighing nearly 75kg. We have also worked with young ladies who are shorter than 1.5m and others taller than 1.8m.
In retro photography, it is all about proportions. You just need to be reasonably fit and healthy and be in reasonably good shape, rather than being any particular size. You also need to tell us honestly what size you are before you arrive so we make sure we have plenty of outfits to fit you.
