Can you check which shirts you purchased ?
Sorry it took so long to get back to you, I snagged the following, feel free to ask anything about them!
Performance T-Tee Cooling Blue: M
Organic Joggers Navy: M
Performance Socks (not personally a fan as they aren't very thick or cushioned but I'll definitely still wear them)
Performance Tee White/Navy & Melon: M
Excellence Polo Navy: S
Off Court Jacket: M
For reference I'm 5' 7" 152 Lbs. The Mediums drape a little lower on the waist which is fine, the Smalls hug the chest a bit but not the belly which is great for all that body dysmorphia that sometimes comes from tighter fitting shirts lol
I think the biggest winner for me is the joggers, they're incredibly comfortable on and off court. Melon polo is also a great look, jacket fits well and easily folds up the sleeves without looking awkward for my short arms. I'd feel comfortable playing a match in pretty much any of the articles I picked up except the socks.
