Some men can pick the best outfit effortlessly. Others struggle to match a shirt to their tie. If you're a guy who would like to look good but doesn't know how, start by building your sense using these sites for outfit ideas and inspiration!

There are degrees to this, of course. Some just want to wear colors that match and clothes that fit right. Others want a little more advice, like pairing accessories or finding trends. And then there's grooming, an often overlooked aspect.

Depending on how much effort you want to put into your look, there's something for everyone here.

1. /r/MaleFashionAdvice (Web): Understand the Basics of Style and Clothes

The first step in looking better is to understand just what you're doing. The material you wear, whether it's cotton or linen or denim, makes a big difference. The fit of your clothes is paramount. Such basics are essential knowledge. Reddit's r/MaleFashionAdvice community teaches you everything you need to know if you're a dummy.

For example, read the beginner's guide to building a wardrobe. Updated regularly, this serves as the starting point for anyone who wants to learn the basics of style. Daily and weekly threads will let you ask questions, learn about specific types of clothes or fashion, and pick clothes by popular vote.

Like we advise in the awesome guide to Reddit, make sure you check out the sidebar before you jump in, which is full of information. You may also want to check out the various other useful subreddits for men's style and fashion.

2. Haute (Android, iOS): Pick Matching Colors

Haute has a simple objective. It wants to make sure you aren't going to wear colors that clash, and instead help you pick matching colors. The app's simplicity makes it a must-have for anyone who struggles with what to wear in the morning and it's an excellent fashion app for Android and iOS.

Start Haute and it'll ask you to choose whether you're male or female. Point the camera at the shirt or pants you're wearing, and pick its color. Haute follows the basics of color theory. The app suggests complementary colors, triads, and other basic color pairings. The options are divided into different types of outfits, so you have a little more help in deciding what to wear.

The free version has some basic options, and if you like it, you can unlock different types of color theory patterns for a price. Haute is wonderful and simple. It's only flaw now, is that it works with solid colors and not patterns.

3. Stylebook Men (iOS): Manage Your Wardrobe

Stylebook is arguably the best fashion and style app on the planet. Separating the apps for men and women also makes its smart suggestions a lot better. Be warned, it's an app that requires effort during setup. If you're a casual user who wants to do the bare minimum to look good, Stylebook isn't the app for you.

The first step is to completely catalog your wardrobe, which Stylebook makes pretty easy with its software. Make sure you have a bedsheet with a solid color (preferably white), lay clothes on it, take a photo, and remove the background with its easy software. It just works. Once you're done, tag the clothes with Stylebook's built-in suggestions. You'll soon have a virtual representation of your entire wardrobe.

Using this, Stylebook makes smart suggestions about what you should wear. It also encourages you to note which items of clothing you wear every day. That way, you'll be able to calculate whether the money you spent on that expensive shirt was worth it or not. Plus, seeing what you wore in a calendar form can help you avoid repeating outfits regularly.

There's a lot more to Stylebook, like a built-in shopping app, notes for clothes, "outfit shuffle" ideas, and more. Check it out. If you spend the time setting it up and using it daily, it'll become your free personal stylist over time.

4. Real Men Real Style (Web): The Best Men's Fashion Resource [No Longer Available]

From tying a knot to knotting a tie, Real Men Real Style (RMRS) has everything you would need to know about being dapper. Founder Antonio Centeno has a huge following of men (and partners trying to make their men look better).

You can read articles on almost any subject, download free ebooks on different style aspects, and even learn about grooming. Antonio also runs a vibrant YouTube channel, which is the best demonstration of his expertise.

RMRS is one of the best men's fashion and style blogs to follow. It is even available as a mobile app, which is brilliant when you want to browse RMRS's large database of infographics. Use those instead of the mobile site, which doesn't have a good experience.

5. Famous Outfits (Web): Cheaply Copy the Style of a Celebrity

Ryan Gosling always seems like he's dressed immaculately, so the easiest thing to do would be to copy him. Chances are, you don't earn as much as Gosling does, so you need cheaper alternatives for what he's wearing.

Famous Outfits tracks a new celebrity's attire every day -- one male and one female. And rather than talking about their designer clothes, Famous Outfits tells you how to recreate that look with inexpensive items from smaller brands.

Apart from the new outfit every day, you can browse through collections (like tie and jeans) to see a popular look and how to pull it off. And of course, you can directly find your favorite celeb and see their looks to emulate them. No wonder Famous Outfits is one of the 21 best websites every man should know about.

What Did We Miss?

There's obviously no shortage of websites and apps that try and teach men the basics of style and fashion. Style Girlfriend, for example, is an excellent resource too. And the newly launched Very Good Light is perfect for millennials and Generation Z.

Have you got a favorite app or site that helps you or your fella make better fashion choices?
