I know this is an old post, but I hope this message gets to you.
I have the same exact body shape. I'm tall and wear a size 5, and it still plagues me (though at least it's not as prominent now since I've lost a bit of weight). I hate feeling like I can't wear anything form fitting. Other girls can flaunt their body in a tight dress and look sexy, and I feel like I couldn't get away with that even if I wanted to. I've never worn a bikini. Until a few years ago, I always wore a t-shirt and shorts over my bathing suit when I went swimming.
It's still a struggle, but even though I can't say I'm thrilled with my body I've made some progress. One thing that's helped is that lately, all of a sudden, there's been awareness of the hip dip. I can remember googling it every way I could think of a few years ago, and finding NOTHING about hip dips. It was like I was the only person in the world shaped this way. I thought I was abnormal.
But now there are entire blogs, Reddit threads, and Tumblrs dedicated to hip dips:

Those are just a few. But if you're like me, it makes you feel better just knowing that this is actually pretty common (just under-represented in media), and you're not deformed. Maybe you're not at the point yet where you can find your body beautiful (I'm still working at it), but at least it's not hideous!
I've even started seeing a lot of models with hip dips. They used to be non-existent, but I notice them frequently now. So there's a small victory.
When it comes to bathing suits, if you're too self conscious to bare all, wear a retro swimdress. I would still be wearing t-shirts and shorts in the pool if my best friend hadn't bought me this adorable vintage swimsuit. It has a skirt that starts high up on my waist (the part where I look thinnest), and then ruffles out over my "bone handles" and dip. Not to be confused with the frumpy old lady swim dresses you see all the time. This style is shorter, but still long enough to cover what you want it to. And it's CUTE. I get compliments on it all the time. Here are some examples:

^That's just like mine! Only mine is black.

The only downside is retro swimsuits are usually pricy (because they're so stylish!). My friend bought mine second hand for only $15 from an etsy shop. So look around for a good deal, or make one yourself. The design is very simple, so you don't have to be an experienced seamstress to make one.
When it comes to everyday clothes, wear peplums for a flattering silhouette. I've even gotten away with wearing a tight pencil skirt, by wearing it with a peplum blazer. It made it look like I had an hourglass figure. The peplum just has to start at the narrowest point of your waist, and be long enough to cover the dip.

You can also wear pencil skirts if they're made from a stiff fabric (as opposed to a tight, stretchy fabric). The key is to have a waistband that fits snugly around the narrowest part of your waist, but then puckers out a bit to create a rounded shape at the top. It creates the illusion of smooth, rounded hips, completely hiding your hip dip. Basically, you want a structured skirt instead of a flimsy piece of material that conforms to your body.

I have a suede skirt like this in a different color, and it's perfect if I wear it high-waisted.
When it comes to jeans, after years of frustration (only being able to find low-rise jeans that cut right into the dip and emphasize my "muffin top"), higher rise jeans are now easier to find (without looking frumpy). What works best for me are jeans that hit an inch or two below my belly button. If you can afford it, Not Your Daughter's Jeans is a great brand that makes mid-rise and high waisted jeans (I can't afford it, but I won a pair). I've also scored perfect jeans at secondhand stores. And once again I must emphasize the advantage of basic sewing skills. I often buy pants at Goodwill that are way too big, and just trim the outside edges off to make them whatever size/fit I want them to be, and then sew them back together. Custom fit pants for as low as 50 cents.
Long, loose cardigans and vests can hide just about anything. Circle skirts, fit-and-flare dresses, a-line skirts, and maxi skirts/dresses are all great choices.

I hope these tips help. I just felt compelled to share my experiences with you so you wouldn't agonize over this issue for years, like I did. Good luck in learning to accept your body, and finding others who love it even when you don't.
