A funeral - Yes, probably a choice of two dresses
A formal work presentation / meeting - I always dress pretty smart in dresses, although probably not formal enough for court. I have never been called to court so far in my career, but it's possible. I would probably go with the black dress suitable for a funeral.
A party in a fancy bar or similar - Yes, lots of dresses
Dinner & drinks where its dressier than jeans - Yes, lot of dresses
A gig - I own a pair of jeans, that could go with a top. Might wear a dress/skirt depending on venue
A walk in the countryside / forest etc - Yes, I have about 10 pairs of walking trousers to cover different options e.g. summer weight quick drying, fleece lined winter ones. Waterproof. Multiple base/mid layers. Hiking wellies, walking boots and two pairs of walking shoes. I walk and travel a lot
A date where you'd like to impress / make an effort - Yes multiple dresses
Regular work from home or office day that's not pjs or gym gear - Yes, have lots of options, such as non gym leggings and long tops/wooly jumpers
I also have a range of suitable gym gear - different lululemon leggings and tops for pilates/yoga Vs body pump
I have a triple wardrobe and a large chest of drawers. Out of season clothes go into the built in wardrobe in the spare room and get swapped around in summer/winter.
I have multiple coats for different conditions summer/winter/waterproof/long/nice (not for outdoor pursuits)
I do spend a lot of time traveling away for a week or two at a time, even up to 17 nights away on walking holidays so that does account for a lot of the range of gear. I go to the gym 4 times a week.
Although I own loads of walking trousers, I don't have any 'normal' trousers as I wear dresses to work and when going out. I do own two pairs of jeans, but they must be about 10-15 years old and I never wear them.
