I sometimes have the fleeting opportunity to pop in to The Meadows at Camberley. The MOST frustrating thing IMO is that if, for example I want black trousers, there is a place with some of the trousers but if I can't find what I want then I have to go round the branded areas and hunt = waste of time on a fleeting visit.
If the store was sorted as M& S used to be, ie by item, then we'd find what we want quicker.
I am a slight fan of the £15 jeans but wish they came higher up the waist, have to wear a belt to keep them up. I also wish there was continuity of size, one blue pair I have in the same size as the others fits a whole size smaller IMO.
I'm also a fan of 1 style of bra but wish it had a higher cotton content.. Daughter likes their sports bras.
I used to buy all my work clothes from M&S in the 80s to about 20 years ago. Good quality lined wool suits, in classic styles, bought as separates, last forever if you buy 2 skirts (they used to offer a choice of length sometimes, too) or 1 skirt 1 trouser to 1 jacket. Change the outfit's look with a variety of plain and print tops and T shirts in current fashionable colours & prints, & team with different patterned scarves for variety. I'd like V neck T shirts not round neck. Or boat neck. Also your Tshirts are just a fraction too short. Add an inch.
I think a good selection of basic mix & match black/navy/grey workwear trousers/skirts/jackets in both wool and a good quality man made fabric would sell well.
As would a selection of colours of a quality lambswool jumper and cardigan, also in longer length (but please do not sell out of black. Ever.)
I'd also like to see less synthetics - those of us with fine hair don't want it standing on end with static, and we'd also like to see far more Made in Britain. In the '70s, many people used to buy M&S rather than BHS/Littlewoods/Debenhams 'because at least it is Made in Britain'
Finally all your handbags should be branded like the Radley's have the leather dog attached, M&S should have a Percy Pig leather emblem attached. So all of us that buy the Percy Pigs for themselves & not the kids can have a smile to themselves. I actually think it's be quite a marketing symbol.
