What Is Sizing Like at Long Tall Sally? An Honest Stylist's Guide

By Ella Blake – Senior Fashion Stylist & Founder | Tellar – Always honest, unbiased, & unsponsored

The short answer: Long Tall Sally runs largely true to standard UK sizing on the body, so your usual UK number is almost always the right place to start — the clever part is the length, not the width. LTS designs exclusively for women 5’8” (173cm) and over, building in longer torsos, higher rises, repositioned darts and inseams of up to 38”. In other words, a size 12 fits like a size 12 — just with every proportion actually drafted for a tall frame rather than scaled up from a 5’5” block.

And that, honestly, is the whole point. I’m 5’10” myself, and I spent most of my twenties buying “regular” trousers and quietly accepting that my ankles would be on show every January. The first time I pulled on a pair of LTS bootcuts that actually broke over my shoe, I stood in the changing room grinning like an idiot. So let me walk you through how the sizing really behaves, category by category.

Start with your normal UK size

Founded back in 1976 by Judy Rich — herself 6ft tall and fed up of trousers that finished mid-shin — LTS has had nearly fifty years to get its blocks right. The range spans UK 8–24 (and denim stretches to a 28), so for most women your everyday high street number translates directly. If you’re a 14 in Next, you’re a 14 here. Don’t overthink the width — concentrate your attention on length, which is where the brand earns its keep.

Where the fit actually varies — read this before you buy

True to UK sizing is the headline, but width can shift between categories and fabrics. Here’s where I’d pay attention:

Trousers & jeans: Sold with leg lengths up to 38”, which is genuinely rare. The waist runs true, but the rise sits higher than you may be used to — brilliant for long torsos, occasionally a touch roomy if you’re long-legged but short-bodied. Know your inside leg before you order.
Dresses & jumpsuits: These are drafted for extra body length, so if you’re “only” 5’8” a midi can read closer to maxi. Check the stated garment length on each product page.
Knitwear & tops: Sleeves are the hero here — finally long enough — and the body length is generous. If you like a cropped look, size with care.
Footwear: A separate fit logic entirely — LTS shoes run to larger sizes for tall women, so use the dedicated footwear chart rather than assuming your clothing size.

My honest take, by category

The denim is the strongest part of the offer — durable fabric, proper inseams, and shapes from wide-leg to barrel that don’t turn into accidental crops. The coats are another genuine win; I once styled a 6’1” client who’d never owned a sleeve that reached her wrist, and an LTS wool coat changed her whole winter. Where I’d temper expectations is the very trend-led pieces — fabrics can feel high-street rather than premium, which is fair given the price. Buy LTS for fit-critical staples (trousers, coats, jumpsuits, knit), and shop elsewhere for the disposable trend bits.

Where else to shop for tall fits (high street)

If you want to spread your wardrobe across more shops, these are the high street names I rate most for taller frames — chosen for genuine length, not just because they exist:

ASOS — the ASOS Tall edit is the broadest on the high street, and the place I send clients first for everyday trend pieces with the leg length built in.
New Look — a properly affordable Tall range, strong on jeans and casual dresses without the premium price tag.
River Island — reliable Tall trousers and tailoring with a slightly fashion-forward cut.
Next — an underrated Tall collection spanning workwear and occasion, with the brand’s usual dependable fit.
Topshop — the resurrected Tall line is still a go-to for denim and going-out pieces.
M&S — long-length and tall options across staples; their longer-line trousers and knits are quietly excellent value.
Boden — offers long-length options on many styles and tends to run generous in the body, ideal for taller customers wanting print and polish.

Premium picks

Me&Em — a London brand quietly brilliant for tall women, with dedicated longer-length tailoring and dresses cut for height. The price is a step up, but the longevity earns it.
Hush — relaxed, elevated basics that run long in the body and sleeve, perfect for off-duty layering when LTS feels too utilitarian.

Luxury & designer

Max Mara — the gold standard for tailoring that flatters a tall frame. The coats and wide trousers are drafted long and lean, so they fall beautifully on height without alteration. An investment, but a forever one.

Two independents worth knowing

The Sixes — a New York label dedicated to women 5’7” and up, with seriously good work-to-weekend trousers. A lovely under-the-radar alternative when you want something beyond the usual names.
Height of Fashion — a UK boutique built entirely around tall women, championed by tall-style insiders. Worth a browse for pieces you simply won’t see everywhere.
