I don't think I could trust a personal stylist, we might not have anything like the same tastes, and I strongly doubt they could capture your essence.
I currently can't find any brand that I like, for the first time in my life of 49 years. Everything feels the same, boxy and badly designed or in lurid 70's upholstery colours. I suit none of these things. I also can't abide high waists, which often touch my boobs and look lumpy under tops of any length or style.
I think trends have become so ubiquitous that barely two brands have a real, discernible identity anymore, unless they are edging towards the avant garde like Toast, or have a unique peculiarity like Cabbages and Roses. The high street is reminiscent of one, mighty huge store to me, and I can hardly tell the difference between one store and another, even if some offer higher quality.
I like sleek fits, fine knits and cuts that flow close to the body without hugging. I like mid rise (and no the shops do not offer many, the online images prove they are still high!) and wide/scoop neckline. This year I can't locate one single long sleeved white tee that doesn't have a choking neckline. It's all very guillotine inspired 
I can find some decent linen for summer at Wrap, Poetry, although much of it is oversized. I like the White Company in theory, but prefer their pyjamas.
In fact, I would live in my White Co PJ's if I could, as they are the only clothes on the market that bloody suit me. I am slim and average height. This shouldn't be so hard.
I also don't think much of those £400 dresses that keep popping up in dress threads by the same handful of posters. I am tempted to believe they work for these brands....And most of these items are simply more exaggerated versions of what's flying around at Zara, Toast or Kin. If I am going to dry clean a dress, it ain't for every day!
