Going 'wild swimming' next month for the first time .. been told I will need a wetsuit and currently scouring EBay for one
So I don't look a complete numpty when I get there ~there's a changing area at the lake ... what do you wear underneath it ? Swimsuit ? Nothing ? I am not exactly super toned and slim and worried my boobage might end up under my armpits 
Be kind if this is a stupid question !
