The first time I actually needed one wasn’t on holiday abroad, it was the local lido on a Tuesday, swimsuit soaked through, two kids demanding chips from the kiosk, and me stood there in a wet costume because I hadn’t thought to bring anything to throw over it. That’s the whole job of a beach dress. It goes on over damp skin in under ten seconds and makes you look like you planned the afternoon instead of just surviving it.
Sizing on these is a law unto itself, because half of them are designed to be loose everywhere, which sounds forgiving until you realise loose everywhere can mean a neckline that gapes every time you bend for a bucket and spade, or armholes big enough to flash your side to the whole beach. Go by the bust measurement, not the label, and check where the hem actually sits once it’s on, because “midi” on the hanger has turned into “why can I see my knickers” on me more than once. The fabric is where cheap ones show themselves fastest, a thin viscose goes see through the second it gets a splash on it and clings in all the wrong places, while a proper cotton or a decent linen blend keeps its shape, dries fast and doesn’t need ironing after it’s been balled up in a bag with a wet towel for six hours. Check the seams at the shoulder and underarm, that’s where the cheap ones start pulling apart by the second wear, and if there’s a tie or a button, make sure it’s stitched on properly and not just glued at the edge. If you’ve got none of these in your life, start with a simple shift shape in a dark or busy print, no zips, no fuss, something you can pull on wet or dry, over a bikini or with trainers and a denim jacket when the sun disappears at six. It covers everything from a beach day to a barbecue to walking to the shop for ice lollies, right through late spring into early autumn, and it packs down to nothing in a case.
A good beach dress is cheap holiday happiness, and a bad one is a lesson you only need to learn once.
