Aston Formal Wear ask that you try on your suit on your chosen collection day. We have an on-site alteration service which can perfect your fitting – provided that the measurements you send us are reasonably accurate. Please ensure you are measured by a competent professional as there may be charges involved if the details aren’t reasonably accurate. We’re able to use metric or imperial measurements (or both if you wish!) so fill in the details as you have them – no need to convert.
