Do you have a boyish figure without many curves?  While this swimsuit model has curves, her beautiful swimsuit shows us something important.  This is a great suit for the girl who lacks that curvy frame.  The thicker bottoms especially are going to add shape to a thin girls body and detract from a smaller bust. 

If you are very slender and lack feminine hips a skimpy bikini can actually detract from your shape making you look like an up and down stick.  To add an illusion of hourglass shape to your frame try a thicker waisted bikini bottom like this one.  Then, look for a detail cutout in the bottom like what is shown here with the front open buckle on the bikini bottoms.  Pull the bottoms up slightly more on the sides to create a scoop shape.  If you have no waist to hip curves this will give the illusion that you do.

As for the top obviously this swimsuit model is not flat chested yet none the less this is a nice top for a slender girl.  The swirling colors are going to enhance the image of your breasts even if they are relatively flat.  You can go a little open in the front as well pushing the triangles more to the outside as shown.  If you are flat chested and wear too skimpy of a top it will only accentuate a small bust.   This top will create bulk on top instead which is what you want.  This bathing suit suit would work really well on a slender girl who is lacking curves.   Love the buckle and the suit is by designer brand Caffe Swimwear.  It’s an adorable suit for a slim figured lady.
