This is cool because you can wear horizontal stripes and those who don't know your secret are thinking “Wow, she must be really thin- I could never wear horizontal stripes, I would look so boxy, but she looks great!” ;-)
I also think that horizontal stripes can be a great pattern for a curvy girl to rock- with the contrast between our natural curves and the straight lines, it would be impossible for us to look boxy even if it were true that horizontal stripes caused that effect. Stripes are also cool if you want to experiment with mixing patterns- since they are a fairly simple pattern they can go well with floral prints, polka dots, or animal print.
What do you think? Could this be a good look for us curvy girls?
