Is there anything better than throwing on your absolute favorite, most comfortable casual shirt on a Sunday afternoon and just relaxing the day away? It's definitely tough to beat. And, it's even tougher if you've nabbed a seriously stylish option. Don't think casual means sloppy. In fact, we've got some of the coolest casual shirts around so you can sport comfort in style. Plus, we've picked out a little something for everyone; so, whether you're looking for super simple, or something that keeps things easy, but definitely has a little zing to it, you'll be all set to go. Casual shirts never looked (or felt) quite so good!

If you're looking for casual, yet sophisticated, James Perse will definitely put a smile on your face. His 'Casual V Neck T-Shirt' definitely offers the perfect balance between comfortable and cool. This one-hundred-percent cotton short sleeve v-neck t-short boasts tone on tone stitching throughout for a clean cut, cute top. Plus, its relaxed fit will keep you comfortable, yet flatters in all the right places. Boasting a pretty, soft, feminine 'Aqua color' (which really comes off as more of a powder blue,) you'll feel pretty in this perfectly fitted casual shirt.

How does he do it, time and again? What we love about this (and James Perse's casual shirts in general,) is his fine ability to take something simple, and do it in only the finest stitching, fabric, and shaping. With every one of his basic pieces, you always know that you'll be getting a supremely well-done and beautifully fitted garment. (Aside from offer top of the line construction and materials, JP also boasts a far more precise size range, numbered from one to four. Gone are the days of small, medium, and large! His unique sizing enables you to snag the perfect fit for your body type.) And, for those of you wondering what you can pair with one of his lovely cotton pieces, we love a skinny jean or khaki pant. I know you're wondering: what about shoes? Not to worry, pretty much anything from Converse tennis shoes to flip-flops will do the trick. Who knew casual could look so good?

For those of you who can appreciate the look and fit of a James Perse choice, but are looking for a little detailing in your next casual shirt (without compromising quality), you definitely want to check out Splendid. Their 'Striped Tee' is a prime example of a classic shirt with a little oomph. This long sleeve, rounded v-neck top boasts three-quarter length sleeves, complete with banded cuffs. Its Supima cotton/modal combination makes for Splendid's ridiculously soft, stretchy, ultra comfortable feel. You'll definitely not only look good, but feel fabulous, too! We love the playful stripes that accent the plum color and make things a little more fun. Plus, as per usual, we love that this shirt is not only fashionable and comfortable, but socially conscious, as well. (All Splendid tops are made in the USA, and are known for their fiscal and social responsibility.) Pair this fun top with dark wash skinny jeans, or white shorts, and you'll be all set for a fun, totally on-trend look.

Now, if you can appreciate the simplicity of James Perse and the cute detailing Splendid has to offer, but are really on the hunt for something casual, but funky, Free People is definitely the brand for you! Free People's 'We the Free Pocket Tee' is slouchy, sexy, and seriously cool. Boasting a deep scoop neck, draped chest pocket, and curved hem, this is the prettiest, casual top around. Its semi-modal jersey fabric is extra soft, while its contrast stitching along the elbow sleeves and back keeps things funky. We love its grey/plum coloring, and unique abstract black-hued front graphic. As this choice can easily be dressed up or dressed down, you can feel sexy, yet comfortable, and move from day to evening wear with no effort!
