I've been enjoying these little crop tops all summer long (also seen here). I think they add a cheeky and playful vibe to your outfit. For a long time I have thought crop tops were a little tricky to wear. Achieving a fun look, but minus the midriff over exposure situation is actually not too difficult to accomplish.
The key is to try the crop top with a high waist bottom piece. This really helps to visually elongate the bottom half of your body (i.e., your legs) and modestly covers the stomach area. You will find that reducing the mid-section gap to expose just a sliver of flesh actually creates a more modern, ladylike and comfortable style rather than a provocative look.
On a slightly separate note, I'm not sure if you feel the same, I can't believe it's pretty much mid-September! Where has the time gone??!! I hope you've been having a fabulous summer! I can't wait for what's to come!
