True. I've always bought my basics in MnS, even when I was a trendy young thing, so bras, knickers, tights, t-shirts. They lasted for years and the t-shirts kept their shape. Now they go all misshapen after the first wash and no amount of pulling rescues them.
Sizing also weird, some size 16 jeans fit, others won't come up over my thighs, and more will gape at the waist.
Jumpers - pill and shrink. Also, why are so many things done in weird colours? I might go looking for a shirt in khaki, but their shirt will be a mucky shade. Yellow - either anaemic or luminous. And as you say, find something in a nice shape, it'll have a huge gapey neckline, or random lace, or mismatched buttons.
As for their knickers, last multipack had 2 pairs where the gusset wasn't fully stitched to the leg. As for the width of their gussets, even when I was a skinny little thing they would've been too narrow. Most uncomfortable, I often feel as if my fanjo is eating them up.
Best places for multipacks now are Primark or Tesco.
