There are plenty of homegrown stars making waves abroad in anything from sports to film, and a lot of them are helping to prove that us Irish guys have a great sense of style. 

Two of the biggest stars at the moment who are representing Ireland on an international stage are Michael Fassbender, who shot to fame thanks to big roles in movies like Frank and X Men; Days of Future Past as well as Rory McIlroy, who is the current world number one, and only looks set to go from strength to strength for the foreseeable future. When it comes to style, they're also leaders of the pack, which is why, along with our friends from Arnotts, we've chosen to take a look at what they're doing right for this Spring/Summer 2015, and take some inspiration for our own wardrobe for this season. 

Michael Fassbender

The key to Fassbender's look is his take on a relaxed and smart-casual style that isn't too difficult to replicate ourselves. Pairing a tshirt with a blazer is a great look for Spring, but is one that can easily be gotten wrong if the colours don't work well together. Take your inspiration from the star of Frank here whose look works for any occasion, whether you're headed to a dinner party or just grabbing a beer with the guys. 

The darker shade of the Gagliardi blazer (€299) contrasts with the light colour of the Penguin t-shirt (€35), while the feature pocket allows you to work in some floral print, something that's right on trend for this season. Those tones of grey and blue are also picked up in the rest of the outfit with these Replay jeans (€110) and Kurt Geiger brogues (€150). The splash of colour on the sole and through the laces plays well with the other shades in the rest of the outfit, while they also mark your footwear out as a cut above the rest. 

Accessories can make an outfit much more versatile, and that is the case here with a look that transfers from the red carpet (as Fassbender himself shows) to the bar on a warm summer's evening. You can add another dimension to this and make it the perfect travel ensemble by choosing this light Cushendale scarf (€25), perfect for keeping the chill at bay of a fresh Spring morning, and this Calvin Klein bag (€300), which is just the right size for a weekend getaway.

Rory McIlroy

At just 25-years-old, Rory McIlroy has the world at his feet, and has become the most recognisable name in the world of golf, so much so that EA Sports have chosen him as the face of their revamped Tiger Woods Golf franchise. Apart from completing every kid's dream in getting his name emblazoned all over the cover of a video game, McIlroy is having a great year on the course, and as a strong favourite for the Masters this year, he might join the golfing elite in becoming one of the few people to have ever won all four majors; this is definitely his moment.

When he's not on the course, the man from Holywood, Co. Down looks as comfortable on the red carpet as the regular A-list stars of Hollywood, California, mainly thanks to his ability to pick the right colouring and fit for his outfits. McIlory knows how to make a classic grey suit work for him, and this Spring Summer that particular piece is once again proving its worth as a staple for every man's collection.

Grey works very well with fairer skin colours, as McIlroy shows below, but if you want to stand out from the crowd and mix things up for this season, you can put a slightly different spin on a classic. Our recommendation is to work a subtle pattern into your suit where possible, which not only makes for an eye-catching ensemble, but also gives you the freedom to split it and use the jacket and trousers independently. This Ted Baker suit (€509) with a blue check running through it is one that perfectly encapsulates that, and pairing with with a crisp white shirt from Strellson (€75) will make this a perfect look for any occasion. 

Whether you're headed to a wedding or a day at the races, accessories make the difference. Turn the suit into a three-piece with this matching Ted Baker waistcoat (€145), something that gives you a tailored look, while at the same time adding the comfort and confidence that being able to layer pieces can give. This Altea tie (€50) sits nicely with the check of the suit and will help to pull out the shade of blue running through it, while a tie bar, like this one from Paul Costelloe (€30), should be in every man's dresser whether you wear a suit on a daily basis or once in a blue moon: it makes sure that the sleek, clean lines that you've worked into the outfit stay that way all day. 

Adding these Simon Carter cufflinks (€79) will add an eye-catching detail that will just peak out from under your sleeves and show that you've put together a full outfit, not just thrown a suit on. This watch from Calvin Klein (€344) in black will be different but not out of place in your look, a classic formal timepiece that can also transition into your day-to-day outfits. As McIlroy shows above, it adds a pop of detail when you need it most, like when you're accepting an award for your overall brilliance, which we're sure will happen any day now for us...

When it comes to footwear, a classic brogue is never going to go out of style, and this design from Oliver Sweeney (€270) is timeless and versatile; they can work as well with a suit as with a pair of slim fit jeans or chinos for a more relaxed vibe.
