My SLP stuff is all pretty mild.
Olive MA-1, PC teddy, mid gray double breasted overcoat from I think FW14?, SS16 knee patch denim, nightriders, Hedi 30 high (calf and suede), old D01 coated from one of the early seasons, Wyatts (suede forgot which season but old, black calf chain), Santiags (suede), black/white SL10, white lows. I'll probably pick up an L17, maybe a shirt or two and a scarf and call it a day.
I find SLP knitwear in general to be pretty underwhelming. Minimal interest in the T's.
@jwoowoo does it better than most. Not just in SLP.
My advice is to not be fixated on just the permanent collection when you start stocking up on slp items when Hedi leaves. I look more at pieces outside of permanent collection and just ask myself "is this wearable for multiple seasons?" Just my 2 cents, this may be obvious to everyone already. Example of this below. The jacket is from 2014 and is not permanent collection, but it still can be worn for multiple seasons and is a NICE piece. Just a classic shearling A-2 bomber with really nice leather and shearling colllar color. Cut on the jacket is aso perfect. Only thing permanent collection in that fit is the black D02's.
