Can somebody help me pick a type of bathing suit to buy?

Yes, that would work. But if not, any one-piece or tankini would cover up tummy fluff. Get something with a pushup top like the one you showed us and/or use sparkly lotion on your legs to draw eyes to better features. And trust me there probably will be fat girls who wear nothing that covers their extra fluff. Be confident with that piece of knowledge. Hope this helps.

The Best Swimsuits for All Body Types [Slideshow]

Swimsuits in flattering fabrics and clever cuts that are suited for real bodies.

Find Your Best Swimsuit

If the results of an informal office poll are any indication, there are few things, when it comes to clothing, that give women more anxiety than the swimsuit: First, there’s the process of weeding through the multitudes of possibilities, and then there’s the actual wearing of it. Finding the right suit—one that’s designed for your figure—can go a long way toward quieting that anxiety. We’ve done the weeding to find a dozen suits meant to flatter women with different body types: those with large chests, those with a tummy they want to camouflage, those with full hips and thighs, and those with straighter shapes. So let the sun shine—we’ll see you on the beach.

Get tips on how to find the best swimsuit for your shape, including, for the full-figured, a dozen flattering plus-size bathing suits.

heidi klein swimwear is all about accentuating your best parts whilst covering the parts of your body that you don't feel as confident about.

They do a series of swimwear ranges called 'your perfect fit' which I found helpful.

They include; 'support bust' and 'd-g cup'

I also really like pairing the swimwear with their maxi dresses and playsuits which I've bought in the past to cover up at the beach bar!

I always say though, if you're having day when you're not feeling 100% confident i'll always go back to black.

Check out heidi klein's black essentials - they're pretty good too!

If you must know, a big-ish belly isn't bad at all, in fact women back in your grandmothers time were actually wanting to be more 'robust' it's something I don't get nowadays, women always want to be stick thin, but they'd be perfectly fine being who they are, but if you really want my two cents on it then I recommend you get a one-piece bathing suit with a swimming top over it (something that looks like a blouse), that way, your legs show, and your chest, depending on the blouse, can be perfectly visible but not in a risqué fashion, of course, this is just for casual swimming, if you want to be more aqua dynamic, then I recommend just a normal one-piece, people won't judge you'll, they'll be too busy eating your dust if you're a fast enough swimmer and you're racing! However, black IS slimming, so if you have a choice go for a black bathing suit
