I am size XS but got size S, just in case. This top is for a baby orangutan with long arms (the sleeves are very long) and with no head (it is impossible to put this top on). There is nothing special about this item, just the name. A waste of money.
I am a true size 2 for jackets , this is somehow very amazing cut even it is larger than my expectation. Means you can size down (for this jacket). Superb material, flattering boy-ish look, cool style. I will be sure wear it with my track pants . Overall it is a very nice jacket.
I was looking for a rucksack for a really long time. Love this one, it is nicely made and very spacious. Sporty, but not too sporty, can also carry it with a cool outfit.
Bought this in size M which on the label is stated as UK 10 and French 38, which ought to translate to S (US 6). It still fit fine on US size 8 - it does stretch. Thick, heavy weight. Compliments an hourglass figure.
