Age appropriate bikinis for <a href=teen girls” width=”749″ height=”435″ />As a Mum to an almost 14-year old, finding suitable (age appropriate) bikinis for teen girls is becoming an annual palaver. 

Like many girls her age, Flea loves swimming, and being on the beach. But it’s increasingly important to Flea that her swimwear looks just right.

My girl used to be happy with board shorts and a rash vest I’d choose from Boden. These days, it’s got to be a bikini, and she’s ridiculously particular about designs.

But then – so am I.

Flea is 13, not 20. She doesn’t need teeny triangles or something that makes her look five years older than she is. She needs strong straps and decent coverage.

Because when you’re a young girl, nothing’s more inhibiting than worrying you might inadvertently flash some strangers on the beach. And when you’re still at school, your swimwear shouldn’t involve the need to shave your bikini line (imho).

Last summer, after a lot (seriously, a LOT) of hunting we found the crop top bikini at the top of this page. It was in the girls’ range at River Island. Flea thought it was really cute, and I was also happy with the coverage. There are loads of designs available in this year’s collection.

But River Island only provides these suits in sizes up to 11-12.

Newsflash, River Island: just because my girl is over 12, doesn’t mean I want her wearing these items…

Honestly, it’s a similar story at a lot of my go-to retailers. Either the girls’ swimwear stops at age 12, or is too revealing, or it goes too far the other way. 

Come on, Boden. No 13-year-old that I know wants to be wearing the same as the 5-year-old who’s building a sandcastle down the beach.

Okay, enough complaining.

We’ve put in the hard work so you don’t have to. Here are 12 fab bikinis for teen girls. We reckon they’re cool enough for the most discerning teen. But they’re practical and modest enough to please parents, too.

12 of the Best Bikinis for Teen Girls & Tweens

hollister teen girl bikini

Hollister Girls’ Crop Top Bikini, £26

This top is really quite modest, and there are a range of bottoms to choose to match if you don’t like the suggested style. It’s a great bikini option for a teen girl.

It’s simple black style is classic and definitely gets teen approval in our house.

nike teen girl bikini

Nike, High Neck Bikini, $50

Not gonna lie, this range is pretty expensive as far as bikinis for teen girls go.

But if you have a child who’s going to be swimming, surfing or doing lots of sporty activities this summer, this design is available in various colours, with co-ordinating throw-over vests, cover-up dresses and leggings. Order it here.

bikinis for teenage girls

Debenhams, Black Ribbed High Neck Bikini, £11.99

Debenhams has very little in the teen-friendly range in its women’s styles this season but we did find this good value high neck bikini top that’s great for teens, with a range of separate bottoms to choose from.

It’s a classic black and should be flexible to go with lots of different items, as well as working as beachwear when your teen is out of the pool! It’s currently on sale at £11.99!

bikini for teen girls

H&M Sports Bikini, £12.99

Looking for a sporty bikini for a teen girl?

I love this design, and Flea’s a fan too. And you can’t really argue with the price, can you? Perfect for light use around a swimming pool, I reckon. It’s available in a whole range of different colours and patterns here. H&M’s children’s bikini range goes up to age 14+ making it ideal for teens.

new look teen bikini

New Look, Girls Tropical Bikini, £12.99

New Look is another retailer who offers kids’ swimwear up to 15, and this season there’s a great range of bikinis for teen girls.

I like this bikini because it’s a more grown up top shape without being TOO revealing and the bottoms are fairly substantial for younger girls. This one is one of Flea’s favourites this season.

bikini for teen girls

New Look, Red Hawaii Tankini, £14.99

Another great teen bikini buy from New Look, this Hawaiian print is a gorgeous colourful option for the summer holidays – and it’s on sale right now! We love this bikini – perhaps partly because we’re feeling a bit sentimental about our trip to Hawaii right now…

bikini billabong

Billabong, Dos Palmas Bikini Top, £48

Billabong is at the more expensive end of the range if you’re looking for a bikini for teens, but Flea and I both though this palm leaf design was really pretty. I’d probably buy it now that Flea’s unlikely to grow too much in the next year, but maybe I’d have skipped it when she was a tween.

It’s available for £48 on the Billabong site in several colours, and with different co-ordinating bottoms.

sunuva bikini teen girls

Sunuva, Crop Halter Bikini, £42


Sunuva actually has a section on its site devoted to young teens aged 9-14, with loads of mix and match options including bikinis, shorts, rash vests and crop rash vests. Everything has 50+ UVA protection, which is always a bonus in our fair-skinned family.

I would say, 100% this is one of the best range of bikinis for teen girls that I’ve found. I love that Flea can swim on the beach, add a pair of shorts, and be instantly ready to pop for lunch somewhere. Check out the range here.

One thing to note – the teen bikini tops (as opposed to the crop tops and halters) are teeny tiny triangle things and won’t cover up your teen’s chest if they’re anything above an A-Cup. I had to confiscate Flea’s before she had a chance to cause a public incident!

matalan teen bikinis uk

Matalan, Rainbow Bikini, £10

I love a good rainbow print and while this cheerful and bright bikini isn’t entirely Flea’s taste, I LOVE it. If you’ve got a teen who likes to be SEEN on the beach then this option from Matalan might fit the bill.

abercrombie teen bikini

Abercrombie & Fitch, Long Line Bandeau, £25.50

This item is is a low-key design that’s perfect for Flea, and actually the one she chose this summer. It’s available from an XXS so will fit most young teens. Also: buying from A&F actually earns me 50 bonus Cool Mum points because it’s a Teen Approved Brand. Parents of other tween and teen girls will understand what I mean by this. Available from XXS here.

tommy hilfiger bikini

Tommy Hilfiger Red Bikini, £33

This option from Children’s Salon is sporty, and looks like it would suit active youngsters without any worries. It’s available up to a size 14-16 and you can order here.

monsoon bikini age 14

Monsoon, Hollie Bikini, £18

Honestly, I just love the design of this bikini from Monsoon. It’s colourful, but sophisticated. And it’s available in sizes from age 7 to 15, making it perfect for tweens and teens alike. Check out the Monsoon site here.
