まず、こちらの服はアジアサイズで製造されています。
後、実際に貴方を見たわけではないので入る入らないの断言は出来かねますので予めご了承ください。
それをふまえて身長5'5、体重150 poundsの方ですと、165cmで68kgくらいの方かと思います。
日本でしたら通常、SかMサイズをオススメすることが多いです。
Lサイズですと、身長が5'9以上無いと大きいかと思います。
ただ、アジアサイズは総じて手足が短いのでLサイズでも良いかもしれない。
曖昧なアドバイスで申し訳ない。
I can not say for sure if it fits you as I haven't seen you in person.
Having that said, I estimate that a person with 5'5 in height and 150 pounds in weight equal to about 165cm in height and 68kg in weight.
In Japan, I would recommend either size S or M.
Size L should be too big for a person with smaller than 5'9 in height.
However, sleeve length and inseam in Asian sizing are shorter in general so size L may be right.
I am sorry that I can not give you a concrete advice.
Also please note that we are not 100% sure whether the clothes may or may not fit with you because we actually have never seen you face to face.
Upon that, we would imagine that your height and weight are 165cm and 68kg based on your data, 5'5 and 150 pounds.
Then, we would mostly recommend S-size or M-size to Japanese customers.
As for L-size, it would be too large unless your height is taller than 5'9.
However, Asian sizes of the length of arms and legs are relatively shorter, so L-size might be still good for you.
We are sorry that we cannot provide you a sharp and exact advice.
Besides, please understand that we cannot tell you whether they fit you or not because we have not actually met you.
Based on that, a person with the height of 5'5 and the weight of 150 pounds almost equals a person who is 165 centimeters and 68 kilograms.
In Japan, we usually S or M size for the person.
L size will be too large unless your height is more than 5'9.
However, because the Asian size is made for those who have shorter arms or legs, L size may fit you.
I am sorry for the ambiguous advice.
Second of all, I couln't tell if it fits you since I've never checked your size.
But I think your height is 5'5 and weight is 150 pounds, it'd be 165cm and 68kg.
For Japanese I usually recomend Small or Medium. Large would be a little too big if you're not more than 5'9.
But Large might be better because Asian clothes usually have shorter arms and legs.
I am sorry for the vague answer.
