DOESN'T FIT RIGHT

Just because it says available in Tall sizes doesn't mean it's meant for you. 

When purchasing tall pants from a store or online, it's not impossible to try the pants on and you have the length but in other areas, your hips, waist, inner thighs, they don't fit. I know from experience that I have bought a pair of pants or two and there was a gap and the pants didn't fit in the waist, hip, butt area, but I kept them. I didn't think I had a choice because the stores that sold tall clothing was very limited, but today is different. There are options. Few, but more than what there use to be.

My advice. Don't keep them! Return them! Exchange them! If it doesn't work for you it's got to GO. If you want to get it tailored because you just gotta have it, fine, but don't settle. I love Alloy's pants and Torrid's jeans. Not only do they have the length but I don't have the gap between my thighs. Torrid caters to plus size, so I think that is the reason why their jeans fit me so good, but they are not a tall girl store. They only carry two jeans style that come in tall. Alloy caters to average sizes, but they have a tall girl division with many options.

Because tall girl clothing is limited alot of stores don't have a tall girl section. That makes it hard to try clothes on before you buy them. Which leads you to buying online.  Th downfall of this is you may have to return or exchange if it doesn't fit. Word of advice, give yourself time to try it on, return it, and exchange it. Unfortunately, that will not be the case all the time.

Bottom line is don't settle. In Clothes, In Length, In Life, In Anything. No exceptions!
You deserve the best.
