ZARA BLOUSE, £29.99

100pc viscose, wash at 30 degrees

WHAT: An expensive looking, silky-feeling shirt. The side seam is fragile looking; one gentle tug and it’s ripped. HOME TEST: This came out of the washing machine incredibly creased. After ironing it was found to have shrunk by five per cent. After just one wash the ripped seam had come undone.

LAB TESTS: Despite the rip, the seam strength is acceptable, but the fabric strength is weaker. Jim says: compared ‘This makes to the others.’ it more susceptible to tearing Zara did not respond to a request for comment. 30 WEARS? NO
