Finding the right fit

Micro bikinis are all about ensuring you have the best fit possible to achieve the tried-and-true look. The best way to do this is to try on several bikinis until you land on one that feels just right. What does just right feel like? Here are some of the qualities you should look out for:

• Bra size: Does the cup cover up while also leaving little to be desired? The goal is to simultaneously have the bust covering the bits while also having a good chunk of the skin showing for that daring touch.

• Bum size: A cheeky look is certainly a head-turner. But mostly when it’s done the proper way. Micro bikini bottoms should teeter that fine line between thong and skimpy. The bottom has small to medium coverage.

• Support: Although they seem like it, micro bikinis are not gravity-defying, meaning you’re going to need a little more help from time to time. This could mean searching for pieces with strings or straps for additional hold. It could also mean heading out to buy clothing tape for more security.

Feeling confident in daring micro bikinis

Wearing micro bikinis can come with some drawbacks, including not feeling very bold and brazen in the swimsuit. This is natural, as wearing itty-bitty bikinis shows off a lot of skin and can even leave you feeling more bare than you do without clothes. Fortunately, there are ways to ensure you don’t arrive on the beach ready to throw on a towel and hide.

• Accessories: No one ever said the micro bikini has to be the only star of the outfit. Spruce up your bikini moment by adding various accessories for extra styling points. Necklaces, body chains and adorable beach hats are a great place to start.

• Design: Because the bread and butter of a micro bikini is the style of the swimsuit, the rest is all up to you. Feel your best self by finding swimsuits in your favorite color or design. From here, all you need to do is flaunt your stuff and find that inner baddie each time you put on the bikini.

• Fit: As with any garment, having the proper size does half the work. Micro bikinis that are too small will constantly shift and slip out of place, while those that are too big will appear droopy or have too many gaps. If you can, be sure to try on the micro bikini before committing to the purchase.

Quick tips before you take a dip

Activities: Keep in mind that micro bikinis may not be the best bikini to wear if you want to do more energetic beach activities. They could interfere with pastimes like surfing or playing volleyball. Leisurely affairs could be better suited, like relaxing in Secrets Tides Punta Cana’s pool chairs or strolling on the coast of Cuixmala—to name a few.

Moisturizing: Being in the sun can be a drying task, and the skin often needs revitalization afterward. Pre-moisturizing before heading to the beach and reapplying occasionally until you’re back home is advised. This way, dry and cracked skin becomes a thing of the past.

Shaving: The bikini line is a little more exposed with this style of swimsuit, so it may help to do a quick pass over the bikini area with a razor. Heading to your local waxing store is also an option, as long as you wait between 24 and 48 hours before heading into the water. But then again, if you don’t care for bare, that’s perfectly fine, too!

Sunscreen: No matter how quickly you’re in and out of the sun, sunscreen is of the utmost importance. Protect your skin at all costs, especially with skin-exposing micro bikinis. And remember to reapply sunscreen every couple of hours for round-the-clock protection.

The trend of micro bikinis is rising more and more each summer—get your hands on a set today!
