Where sello starts

What is sello

sello is the clothing platform that builds outfits from your own wardrobe

sello (also known as sty4you, after its domain sty4you.com) is a clothing platform and personal style app. Instead of selling you new clothes, it starts with the ones you already have: you photograph your wardrobe, sello turns it into a digital closet, and from there it puts together your outfit for each day.

What makes it different from a catalogue or a virtual try-on is that sello knows two things no store does: what is actually hanging in your closet, and which colors suit you. A personal color analysis quiz works out your color season, and every combination you see stays inside that palette.

It is free, runs in the browser on any phone or laptop, and is available in English, Spanish, Portuguese, French, Italian and German.

How it works

Build outfits from your closet
in three steps.

1
Find your colors
A 4-step quiz works out your color season: which shades flatter you, which to avoid and which combinations actually work.
2
Upload your closet
Photograph your clothes. sello sorts them by type, season and occasion — and knows exactly what you have available today.
3
Get your outfits
Every morning sello puts together looks based on the weather, your plans and your palette. Just pick the one you like.

What you get

An app that knows
what to wear today.

Outfits that always flatter you
Every combination respects your color season. If you're Deep Autumn, you won't see summer pastels — only shades that genuinely suit you.
Built around your weather and plans
Office meeting, rain, 14°C? sello knows. Every suggestion starts from what today actually needs, not from a generic template.
A marketplace filtered by your palette
Find secondhand or new pieces that already work with what you own. No noise — only what fits your wardrobe.
A wardrobe that works for you
sello tracks what you wear, what's been sitting unused and what you're missing. It turns a full closet into a closet that works.
