Tests are not normally needed for someone who has sleep related groaning. Your doctor may have you do an overnight sleep study if your problem is severely disturbing your sleep. This study is called a polysomnogram. It charts your brain waves, heart beat, and breathing as you sleep.
A gingham shirt is a menswear classic and this Gentlemans Corner Felix shirt is no exception. This classic button down style has a slim fit in the upper body with a more generous cut around the stomach.
Play with different patterns like ginghams and tartans which feature similar blue tones for a nod to private school uniforms. Alternatively, go for knitted ties in solid colours like cherry reds and grass greens for a clean, classic way to interpret a navy suit with a white shirt.
