Arbyn for Fashion & Apparel

Sizing, fit, returns. Without the back-and-forth.

The four questions that make up most of fashion support, does it run small, does it fit, can I exchange it, can I return it, Arbyn handles every one. Trained on your size chart, your fit guide, your return policy, and your voice.

Stella · Ridgeline Denim2:14 am
Hi! I'm a US 8 normally, would the high-rise 27" run small? I'm between sizes and last time I sized down it was tight.
Stella · ridgeline-denim.com
Hi Stella, for the high-rise 27" I'd actually go with your usual size 8. Denim from the Crescent line runs true; only the slim straight runs about a half-size small. Your last order was a slim straight, which is why size-down felt tight.

Oh that's super helpful, thank you!

Support and sales, in the same inbox

Eight fashion conversations. Five support. Three sales.

Arbyn isn't just there to answer tickets, it sells too. Half of fashion's inbox is “where's my order.” The other half is “should I buy this.” Arbyn handles both, over email and live chat, in your voice. The examples below use a fictional brand, Ridgeline Denim.

Sizing questionSUPPORT
resolved · 38s
Does the Crescent skirt run true to size? I'm normally an XS.
The Crescent runs true, XS will fit like your usual XS. If you prefer a looser drape over the hip, sizing up to S is what most customers do.

Hi, torn between the slim straight and the high-rise straight. I'm 5'8", usually wear a 27. Mostly sneakers, occasionally heels.
For sneakers + 5'8", the high-rise straight gives more leg line. Most 5'8" customers in 27 land there. Slim straight is great with heels but reads dressier. Either way, your 27 is right. Want me to add the 27 high-rise to your cart?
Yes please!

What do people usually wear with the linen shirt? Just got it in oat.
Oat pairs most with the wide-leg trouser in fennel (relaxed weekend) or the cropped slim in black (dressier). Both in stock in your size. Want a quick look at either?
Fennel please!

Hi Maya! On the Crescent skirt in S green, there are 3 left. I've applied code WELCOME10 to your cart, so the price is locked in whenever you check out.
Oh nice, grabbing it after dinner then, thanks
Perfect, it'll be in your cart with the code applied when you're back.

Trained on your catalog

Arbyn reads your size chart like one of your reps does.

When you connect Arbyn to Shopify, it doesn't just see products, it reads the structured fashion data your support team relies on every day. No prompt engineering required.

01
Size charts & fit guides

Per-collection, per-fit. Arbyn reads tables from your size chart pages and the data in your Shopify product metafields, both.

02
Model measurements

"The model is 5'10" wearing a size S." Arbyn pulls this from your product page copy and uses it in fit answers.

03
Fit feedback history

Past customer notes, "ran small," "great drape," "color is darker IRL", are tagged per-SKU and surface in replies.

04
Return reasons by SKU

Arbyn knows that 31% of returns on the slim straight are "too small", and proactively offers the next size up before the return starts.

Returns & exchanges

Fashion's #1 cost center. Now mostly Arbyn's job.

Fashion returns are 3-4x other verticals. The hidden cost isn't the shipping label, it's the eight back-and-forth emails per return. Arbyn closes that loop in one reply.

Eligibility, instantly

Arbyn checks order date, item condition, sale/final-sale status, region-specific rules, and your custom exceptions in under a second. No "let me check with the team."

Exchange-first, refund-second

Before quoting a refund, Arbyn offers the next size, color, or comparable item so more returns become exchanges and revenue stays in.

Brand voice tuning

Sounds like your brand. Not like a chatbot.

Three different fashion brands. One identical question. Three completely different Arbyn replies, because tone, vocabulary, and rhythm come from the tone you set and the replies you approve. We don't pick a “fashion voice.” You do.

Same customer · asking every store
"Does the Crescent skirt run true to size? I'm normally an XS."
QUIET LUXURY BRAND
Minimal · considered · restrained

It does. Your usual XS will sit beautifully. If you prefer a softer drape, a size up is appropriate.

Yes, Crescent runs true so XS is your size. Want it a touch looser around the hip? Most go up to S. You're good either way.

WARM VINTAGE BRAND

True to size, lovely, your usual XS will fit just as it should. A touch of give through the hip, which is exactly how we cut it. Wear it well.
