How to Find Your Size in Another Tomorrow

By Ella Blake | Tellar Fashion Hub

Another Tomorrow runs true to size for the most part — but this is a luxury sustainable brand that cuts for a relaxed, slightly oversized silhouette, so if you're between sizes or used to more tailored fits, sizing down is often the smarter move. Here's everything you need to know before you buy.

What is Another Tomorrow?

If you haven't discovered Another Tomorrow yet, you're in for a treat — and possibly a small existential crisis about all the fast fashion you've ever bought. Founded by Vanessa Barboni Hallik in 2019, Another Tomorrow is a New York-based luxury womenswear brand built entirely on the principle that fashion can and should do better. We're talking certified organic fabrics, verified supply chains, and a commitment to radical transparency that puts most heritage houses to shame.

I first came across them when I was genuinely trying to invest in fewer, better pieces. I'd been burnt too many times by "quiet luxury" brands that weren't quite as elevated as the price tag suggested. Another Tomorrow was different — the fabrics felt extraordinary, the tailoring was considered, and the fact that I could trace every garment's journey from fibre to finished piece made the purchase feel genuinely meaningful. It's the kind of brand that changes how you think about getting dressed.

Aesthetic-wise, think understated luxury: clean lines, muted palettes, beautifully draped fabrics. It sits comfortably alongside names like Totême, The Row, and Vince — effortless, grown-up dressing for women who've moved well past trend-chasing.

Understanding Another Tomorrow's Sizing

Another Tomorrow uses US sizing (0–12), which converts roughly as follows:

US 0 = UK 4 / EU 32
US 2 = UK 6 / EU 34
US 4 = UK 8 / EU 36
US 6 = UK 10 / EU 38
US 8 = UK 12 / EU 40
US 10 = UK 14 / EU 42
US 12 = UK 16 / EU 44

That said, conversions are just a starting point. The real question is how the brand actually cuts its garments — and Another Tomorrow has a very specific design philosophy that affects how things fit in practice.

How Another Tomorrow Garments Actually Fit

The brand designs with ease and movement in mind. This is intentional — their pieces are meant to feel relaxed and unconstructed, channelling that beautifully undone, effortless quality that's so hard to manufacture on purpose. In real terms, this means:

Tops and knitwear tend to run generously. I'd recommend sizing down if you prefer a more fitted look, or sticking to your usual size if you love an oversized drape.
Trousers and tailoring are cut with a wider, relaxed leg — they're designed to sit at the natural waist with volume through the leg, so focus on your waist measurement first and let the leg do its thing.
Dresses and coats are often one of those "fits most" silhouettes — fluid, unstructured, and quite forgiving. If you're petite, bear in mind the lengths can run long.
Fitted knitwear (their ribbed or slim-cut styles) can come up slightly smaller than expected — worth sizing up if you're between sizes on those specific pieces.

Stylist tip: Another Tomorrow's product pages include detailed measurements for each size — always check the flat garment measurements against your own body measurements, not just your usual label size. It takes two minutes and saves a lot of expensive disappointment.

Taking Your Measurements

Before you buy anything from Another Tomorrow — or any luxury brand, frankly — it's worth getting your measurements properly sorted. The three you need are:

Bust: Measure around the fullest part of your chest, keeping the tape parallel to the floor.
Waist: Measure around your natural waist — typically the narrowest point of your torso, not where your jeans sit.
Hips: Measure around the fullest part of your hips and seat, usually about 20cm below your natural waist.

Once you have those, Another Tomorrow's size chart (available on their website) makes it genuinely straightforward to land on the right size — cross-reference both your bust and waist measurements, as the brand's structured pieces may pull slightly differently depending on where you carry your shape.

Returns and Sizing Risk

Another Tomorrow does offer returns, but given that international shipping from the US adds time and cost, it's worth getting your size right first time. Their customer service team is excellent — if you're genuinely unsure between two sizes, drop them an email with your measurements and the specific item you're considering. In my experience, luxury brands at this price point are usually very helpful when you ask directly, and Another Tomorrow's commitment to customer experience matches their commitment to sustainability.

Similar Brands — and How Their Sizing Compares

If you love the Another Tomorrow aesthetic but want something more readily available on UK shores, here are some brilliant alternatives that share that quiet, considered approach to dressing:

Cos — A perennial favourite for clean, architectural pieces. COS runs slightly slim in the body but generously in length; another brand where sizing up in knitwear is often wise.
Massimo Dutti — Exceptionally well-made for the price, with a similar neutral, understated palette. Spanish sizing, so UK shoppers often find they need to go one size up.
Whistles — Brilliant for relaxed tailoring and fluid fabrics. Tends to run true to size, occasionally generous on tops.
Reiss — Great for elevated occasion dressing with that same clean, quiet luxury feel. Runs fairly true to size but double check on structured pieces.
Me&Em — A genuinely underrated British brand with thoughtful tailoring and beautiful fabrics. Very consistent sizing, runs true to UK standard.
Jigsaw — Cut for grown-up bodies with real fabric quality. Runs true to UK sizing and is a brilliant bridge between high street and designer.
Anthropologie — Slightly more eclectic in aesthetic but often stocks beautifully relaxed, artisan-feeling pieces that share that Another Tomorrow spirit. US sizing applies, so check measurements carefully.
Hush — For the cosy, understated end of the Another Tomorrow wardrobe — relaxed knitwear and linen pieces in beautiful muted tones. Runs true to size, occasionally generous.

For two independent alternatives worth knowing about: Asket is a Swedish brand with a similarly radical transparency philosophy and exceptional quality basics — their sizing tool is excellent, and they offer a range of lengths which is genuinely useful. And Carefully Considered is a British sustainable brand producing thoughtfully crafted pieces in deadstock and organic fabrics — worth bookmarking if Another Tomorrow's ethos appeals to you.
