...and other pressing questions, answered by us. You’re welcome.

For many of us, it’s that time of year when we switch over our wardrobe for the new season – which often means resurfacing well-loved clothes you haven’t worn in a while, and discovering things you might never wear again. But how do you know when to throw stuff away? It’s a question one of our Facebook followers asked this week, and we have a stylish solution, below – along with our thoughts on the rules of sneakers and suits, and buying in multiples.

Keep sending your style-related questions via Instagram, Twitter and Facebook – we’ll answer a selection every Friday.

How do you sort out the clothes you’re just not sure whether you should keep or not?

From Mr Mark Kappert via Facebook

A timely question Mr Kappert, and one I have pondered this very week as I have performed the Ol’ Switcheroo – ie, the seasonal rotation of my wardrobe from winter to summer. This biannual changeover (that all New Yorkers in minuscule apartments have to do) presents the opportunity to conduct a thorough audit of one’s clothing, exhume and discover afresh some that have been buried deep in the inaccessible recesses, and weigh up what to store away and what to bequeath to a goodwill store/charity shop.

A couple of Christmases ago, I was bought not one but three copies of the book The Life-Changing Magic Of Tidying Up: The Japanese Art Of Decluttering And Organizing by Ms Marie Kondo. I think perhaps my nearest and dearest were trying to tell me something. I made a start by immediately regifting the two extra copies.

Ms Kondo’s test for whether or not you should keep something is to ask yourself the question: “Does it spark joy?” The questions I ask are less about joy and more: a) Have I worn this in the last six months? b) Does it still fit and look good? c) Do I still like it? If the answer to all three questions is yes, it stays. One or more nos, it goes. Inevitably you will create “a pile of indecision”, but you need to be ruthless.

The stuff unsuitable for spring that you’re keeping needs to be cleaned (try The Laundress), folded and packed away, ideally in sealed storage bags (check out our complete guide here). The newly edited selection of clothing you’re resurfacing for spring and summer should be carefully hung or folded (I now swear by the ingenious Kondo technique for folding T-shirts, socks and boxer shorts by standing them on end as if they are books in a bookcase). And then the clothes you have purged need to be given away. I am taking two full suitcases home to my family this weekend for my brothers to pick through before taking the rest to charity. I’m nice like that.

When wearing white sneakers with a suit, should the laces be worn out or tucked in?

I understand why you’re asking this question. Your thinking is that with a suit, the shoes should be very clean of silhouette, and laces can look untidy. But my advice is to resist the temptation to tuck in your laces. Firstly, it’s really not comfortable. Secondly, it looks a bit schoolboy. Embrace the lace. If you feel your laces are too long, you can always weave them in and out of the eyelets in a different way – see these techniques from Mr Ian Fieggen, aka Professor Shoelace. Make sure your (presumably white) laces are clean – replace them with new ones if necessary – and that your sneakers look box-fresh. Either because they are, or because you are a dab hand with Jason Markk’s truly excellent sneaker products. Don’t you scrub up well!

Is it strange that I have multiples of the same easy-to-wear basics – such as white T-shirts?

Not at all – and for reasons you have outlined yourself: such things are easy to wear and they are the basics we all need in our wardrobe. And, since they are always available, they are easily replaced (and you should replace them when they discolour). A simple white T-shirt has always looked good since the days of Messrs James Dean and Marlon Brando. But there are white T-shirts, and then there are white T-shirts. James Perse, Derek Rose, Schiesser and Sunspel set the benchmark; I own some of each. But my favourite for summer is actually Sandro’s slub linen T-shirt – I love the handfeel and the way it hangs.
