Hi Jayne,
I don't think I've ever ordered something from Wehkamp, but I do know the company. It's a mail order company like 3Suisse, they used to sell via catalogue only, but now both have websites too. I can't really attest to the quality of their products, but I see there are two reviews for this jacket and I'll add a translation below.
It is a fun jacket, and I love all three colours.
The description says:
Fabric: 65% cotton, 30% polyester, 5% elastane.
Product name: Miss Etam Regulier Blazer
Product description: Single coloured, slim-fitting women's blazer. The blazer has long sleeves with crinkle effect, lapel collar, ornamental buttons, and closes with 1 button.
Review 1:
Very nice, stylish jacket that can be worn both in a sporty fashion with jeans, and with dressy trousers and shirt. Runs small, but I kept it anyway because I love how it looks on me.
5 stars for all criteria: price/quality ratio / meets expectations / like the look and style / fit
Review 2:
Very beautiful blazer. It definitely gets you noticed. Very nice for Summer when it's a little cooler. I got my regular size and it fits well. I'm very happy with this blazer.
5 stars for all criteria.
FWIW: I don't think you need to be hesitant to place an order with this company. The well-known European mail order companies all have a good reputation for speedy delivery and honouring their terms of use.
