I have Kerrits tights for summer which are super comfy. Also have a closet full of Kerrits FS Flex Tights which I thought I really liked until I got a pair of TS mid rise Trophy Hunters. The Kerrits are now redheaded stepchildren and I wear that one pair of TS for every. single. ride.
You might check ebay for used TS if the thought of used breeches doesn't give you the willies. I actually just bought my daughter a pair of MH dress boots for $75 that looked brand new.
I love Harry Hall breeches, but they are so hard to find in the US. All of mine have worn like iron. I'm down to one pair now I will have to try the Horze breeches. I have lots of Kerrits tights, since I lived in a warm climate. Those are great for schooling, but not very warm for where I am now. I've had Devon Aire breeches that I really liked that lasted for years, and was thinking of getting more of them since I now live in a cold damp place where heavier breeches are a necessity.
I got the Grand Prix Hudson breeches on TOTD on sale, hoping they would fit like my TS Trophy Mid-rise. The fabric is nice but I was a bit bummed out that the rise was quite a bit higher. I will have to wear them around the house some more and decide if I can stand to ride in them since I can't stand pants over my belly button, lol. Otherwise they might be on their way elsewhere. The size was comparable between the two for me, 32L in both.
I am asking for a pair of the Horze breeches for Christmas, so we will see how those fit me.
