Ask yourself, how long you're likely to be spending outside. There's no right or wrong to cover ups or sleeves when it comes to the wedding dress look you dream of. Sleeves in summer or strapless in winter, it can all work, and your adrenaline really will get you through anything. I wouldn't compromise your look for the season. Having said that, most brides don't realise that a sleeve can easily be added to a gown. Most bridal brands will allow you to order lace to match. This is a service we offer at Bellissima Brides, enabling you to customise your gown, and make it your own.
