Then you can tell Fitbay which brands and sizes you like. It can be anything – Banana Republic 30×30 chinos, Levi’s 28×30 jeans, J. Crew XS jackets – whatever.

If you want, you can upload your own photo for each item, or you can let Fitbay find a picture from the internet. I like using my own photos so people can see how my clothes actually fit on a regular person, rather than some professional model.

Finding your body doubles

After you create your profile, Fitbay uses some algorithmic wizardry to match you up with your body doubles, people who are built like you. For example, my body doubles are short, slim men with normal shaped torsos.

Some of my body doubles also have shorter arms, which means they have the same problem with shirtsleeves always being too long.

Based on what brands and sizes you and your body doubles like, Fitbay recommends clothing that will probably fit your build.

You can browse recommendations by brand, size or garment type (i.e. jackets):

It’s pretty accurate, so you will probably see some things that you already own. But if you see something you like, you can save it:

So you can use Fitbay to keep a list of clothes you’d like to try on. This is a great way to remember new brands that you haven’t tried yet.

You can use Fitbay on your computer or phone

Fitbay has a mobile app, so you can use it on your phone (which is great for shopping). It has most of same features as the full website version, and its design makes it fun to use.

I prefer the desktop version because I do most of my clothes shopping online, but the your profile syncs with the app automatically, so you can switch off anytime.

You should sign up now (it’s free)

Here’s the thing about Fitbay: it relies on users like you.

The more of us that sign up, the better it will be.

That’s why I want every Modest Man reader to create a Fitbay profile so that we can learn from each other. It’s free, and if you don’t like it, you don’t have to use it.
