Irina, for sure. First, Sandwich has an actual and quite beautiful store on Laurier in Montreal, so if you are out that way you can visit. I will say that if I first encountered them on the website, which literally ought to win the award for the worst website ever, I would never have bought anything from them. But I had seen and tried on their clothes in boutiques in Kingston and Toronto and then Montreal and I knew the fits and quality.
A few general remarks. Sizing is EU. But generous EU sizing -- I don't know if this is true across the board but in my experience German and Dutch garments are cut more generously than French or Italian.
I sized down in the blazer to a 34 for that reason, and also because it has the knit along the back, so it expands as you. move. It also comes in a beautiful bright light blue on the website but since it is a past season item, I don't know what they have for sizes.
Keep in mind that while my shoulders are square they are not broad and my bust is relatively small. To give you an idea, although Angie is 2 inches taller than me, I wear a size larger. So I have a small but not tiny frame.
This jacket is emphatically not an oversized or long blazer. In fact, when Angie did a post on long blazers last year, I think I countered with my "not long" blazer in a WIW.
It's classic in cut, one button, unlined, but with nicely finished seams inside.The fabric is extremely light, as Helena points out. The skirt is definitely high summer wear only in my climate and yours. The jacket is a bit more flexible since it is obviously worn over something else. I wore it on a trip to Ontario in late May last spring and enjoyed it then. I wore it all summer in BC. Till about September, when i wanted different colours/ fabrications.
The back is linen knit. The inside sleeves are linen knit so they stay pushed up if that is your preference (as it is mine). Of course the fabric does wrinkle at the elbows, etc, but the dye (which in the light olive, at least, is variegated in tone) makes wrinkles less visible/ noticeable than it might otherwise be.
The price is more than right. I got it also for this price last year.
Unfortunately, as i said, the website will not help you at all with anything -- it is a leap of faith to order anything from them. They do have a sizing chart, though, and they deliver promptly. The prices on the items I bought (all past seasons so on sale) were pretty much like Old Navy/ Gap prices. For a much, much higher quality and a decent style quotient.
