As I was technically meant to be doing Christmas shopping today I didn't go into very many shops but did have a good browse in JL. I saw and tried the following (all Reiss):
Ice aqua jumper - A good match for Ice Green (shade 30). Good colour but the mesh bit looked very odd on me. I think it would be better on someone will a smaller bust.
Blue lace jumper - Fell between Royal and Electric blue (shades 10 & 11) but still very cool and deep. Alas, the bust line was, again, wrong for me. The sleeves were very tight too. I don't think my arms are freakishly wide but maybe they are...
Chunky grey jumper - Fell between Light grey and Grey (shades 3 & 4) and the metallic thread was silvery too. Looked bloody awful on though! Too chunky on me but would look great on someone very tall and thin.
Green dress - A good match for Light Emerald (shade 27). I tried this as the cut of the body and skirt fit with my style guidelines. However, the V-neck didn't work for me and the armholes were annoyingly big at the sides. Flesh could be seen! The fabric was a great colour and felt lovely (for polyester).
Textured white shirt - I loved this! A good fit (slightly gapey on the thrid button but nothing noticeable) and a true white. The texture fits with my style rules but, but, £95 for a viscose shirt! I didn't buy it as I begrudge spending that amount when I just bought almost identical silk ones (in black and navy) from Uniqlo for £29 each!
There were a lot of grey, blue and black metallic jumpers around and lots of black sequined dresses so if you like sparkle this could be your time!
