What's the most versatile item in your summer wardrobe? If it's not one of the best one piece swimsuits, it might be time to invest.
It goes without saying that their primary purpose is, of course, to wear in the water and/or while sunbathing, but any great swimming costume will have you covered when it comes to activities beyond that too. Planning on going from beach to bar but don't want to bring a spare outfit? Wear your swimsuit as a bodysuit and you're good to go.
Don't get me wrong; summer dresses, sandals, beach bags and linen trousers are all extremely hardworking, but a one-piece is something you'll keep in your chest of drawers year-round – not rotate out when the colder seasons approach.
GLAMOUR-approved one-piece swimsuits, at a glance:
- Best crinkle swimsuit: Square Neck Swimsuit, £175, Hunza G
- Best bandeau swimsuit: Seafolly South pacific Bandeau One Piece, £145, Selfridges
- Best tummy control swimsuit: Tummy Control Padded Plunge Swimsuit, £35, Marks & Spencer
Now those summer travels are filling up our calendars, so too are we browsing our favourite swimwear brands. As such, I'm declaring it officially time to invest in a few new swimsuits (before everyone else beats you to it).
SS25 runway trends (from Chanel, Richard Quinn, Bottega Veneta and Coach) have taught us that, as far as colours, fabrics and patterns go; fairy-like pastels, 3D bows and flowers, and pistachio green shades are where you should set your sights. Good news, then, that this round-up is full of exactly that.
Whether you're planning on spending the majority of the season in your own garden or you've got the holiday of a lifetime booked, now is the perfect time to experiment. Don't have the luxury of any private outdoor space? Not got a vacation booked just yet? Then why not road-test (park-test?) a new one piece swimsuit style slightly more modestly by wearing it with a pair of your favourite denim shorts? After all, the true test of a great cozzie has always been how many times you can re-wear it.
Don't forget to also shop the best bikinis, beach towels, sunglasses and summer hats. We've also got modest swimwear, sports swimsuits and linen dresses ahead of your upcoming getaway. For more from GLAMOUR UK's Senior Commerce Writer Georgia Trodd, follow her on Instagram @georgiatrodd.
