Long bridesmaid dresses are a wedding classic for good reason.
A longer gown means timeless elegance, whether you choose a floor-sweeping maxi or an ankle-grazing hem. But that's not to say that long bridesmaid dresses are boring - far from it.
You can find longer dresses to suit all different wedding styles, from boho prettiness through to sculptural, city-appropriate chic and red-carpet glamour.
One thing to consider is that unless you choose bridesmaids of exactly the same height (unlikely, but possible), you may need to have the hems taken up for a perfect fit for each person. This will also need to take into account whether they're wearing heels or flats.
Speaking of shoes: if any of your bridesmaids is planning on a heel, suggest they practise walking in the full outfit ahead of the big day, to avoid any heel-to-hem tripping incidents.
Of course, not all long bridesmaid dresses are created equal. That's why we've put together the definitive edit of the best you can buy in 2021.
