I had to regift all the size XL crops to my friends who usually would wear a size M, and it fit perfectly. When I first purchased from Leelo I wore a size L (your largest size at the time). I was a size 12 and I found the pants were not squat proof, they rolled down at the waist band and they were quite hot. I wanted to support your brand because you're local and I was looking for a replacement for the lululemon align leggings. I decided it has been several years so maybe you had the opportunity to refine your product (although your marketing and choice of models is still incredibly tone deaf and lacks diversity and inclusion) and I saw that you had expanded your size and colour range. I purchased a few pairs of leggings on sale to try them out and two sports bras. The leggings I purcahsed in XL as I wear a 14-16 in some brands and they still aren't great with the squat proof, but they seem slightly better. The waist band still rolls down and the front seam is weird. The leggins are tight and hot but still somehow not tight enough around the waist. The bras are a JOKE. I fit into a lululemon 10, a LSKD XL and I'm a 16DD or a 14 E. Let me tell you, these bras fit my friend who is a size 10-12 B cup. I didn't even try it on because I knew I wouldn't be able to get it off. For the money I spent on "trialing" Leelo again, I could have just purchased a pair of lululemon aligns and a lululemon crop - but I wanted to support local. I've regifted all my Leelo leggings and tops to my thin friends. I am an active, fit and muscular woman who is tall and just happens to be in a larger body - there is no need for more brands just accommodating to thin women. I hope you do better in the future but this was the last time I am going to drop hundreds of dollars with your company.
If you're petite I'm sure you wont have any issue with the brand. If you're a size 12+ then maybe try something else.
