I am a co-founder of the startup http://www.fitparel.com. It is a hassle free way to shop clothing online.

fitparel.com takes the guessing-game out of size selection when purchasing clothes online. You enter the size of an item that you know fits well and we recommend similar items based on its dimensions. We indicate the size of the apparel you need to purchase and also the quality of fit between the fits-me-well item and the similar item.
