Board shorts

Love them but the website needs to let you know which length you have ordered - According to the label they come in 3 different lengths:- 16", 18" and 20". The medium fit is great but I wanted the longer ones and I have received the shortest ones!:-(

Extremely short shorts

Decent quality and price but these are very very short shorts
