It seems that what makes or breaks the suitability of casual/smart clothing for ‘around the house’ is comfort and washability. Constricting isn’t comfortable, so how to manage ‘loose’ clothing while being intentional about it vs looking like a slob? Athletic cuts in non athletic (looking) fabrics seems a solution. In other words some sort of stretchy waist, or even stretch fabric, in a non-restrictive style - that doesn’t look like you’re wearing yoga pants (but maybe you are?!).
Then there is the washability thing. If there is anything I’ve learned in my ‘counting wears’ experiment of 2020, it is how hard laundering is on clothing. Natural fibres in particular. If part of your personal style is to look crisp, pristine, and sharpe - you’ve got to sort out fabrics that can take the wear and tear of frequent washing - or not have a minimalist closet. I love my green chinos, but the high cotton content has resulted in a softened and faded patina that I’m okay with since it’s part of my style. Someone more fastidious might designate them candidates for the donation bag. On the other hand, the 100% synthetic OTF pants look like new (if you look past the thinning material at the rear.).
Same goes for tops - synthetics (some sweaters, mesh T’s) hold shape and colour better than cottons, wools, and cashmere - and can go through the wash without the form of Russian roulette one plays with the later.
A collection of interesting toppers, including ultra-lite puffers to throw on top of plain or loose fitting tops will reign in volume, create form, and create interest with colour and texture while meeting the brief for comfort and durability. Then there is fun and interesting accessories - hats, scarves, cross body bags or Fanny packs worn bandolier style, etc. Don’t forget footwear! If there is anything I’ve learned from Angie, it’s the power of signature footwear to cement personal style.
Grooming, which you already do so well, Lisa, seals the deal and elevates the whole.
If I had to identify your strengths, I would volunteer that you nail grooming, outerwear (coats), and footwear. I believe you struggle to find satisfaction with tops and bottoms, though from your OOTD pics, there aren’t many faults to be found. If you were to put anything on a ‘no buy’ list, I would volunteer you list oversized and heavy/thick sweaters. Fluid tops yes! Oversized no!
