The biggest concern with shopping for sports clothes is size (I realize that sounds funny, but with other items, like slacks for example, they can be altered id the fit is slightly off). For the most part if you're not sure, estimate one size up. This is true for almost anything - with sporting clothes, you're looking for more movement, not less. With undergarments or any kind, make sure that you understand what the return policy is - it is often different than for other items. Read the site carefully! If you are going to buy running shoes, you can find GREAT deals online. But here's what I'd do...go to a running store first. You can probably find one nearby - someplace like FleetFeet. Have someone who knows what they're doing evaluate your running gait, and recommend a pair of shoes. Then, come back to DressGood.com and search our merchant partners for the shoes you need - you are almost guaranteed to find a better deal.

I'm going out on a limb here - fashion takes a back seat. With sports clothes, always choose function over form. If you can find a color you like or a pattern, great. But when shopping for any outfit that you'll be moving around a lot in, make sure it fits as it's supposed to abd has the features you need, like coolmax, air vents, etc.
