I’m not sure which size for Wunder train to buy. I used to wear the size 6 I thought that might be too small since I gained weight (5-10lbs) and I’m 5, 3. The newer Wunder trains feels tighter. When I try the size 8 in store they feel ok but there’s bunching at the crotch/upper thighs. My old size 6s look smoother but the new ones in store seem too tight, I can get the size 6 on but it’s harder and there’s some muffin top at the top when I try on the ones in store. I also noticed the 8s I buy online come tight in the ankle area while the ones in store are looser, I’m guessing the ones in store were tried on more, both have the gaping at the crotch/upper thigh. Should I get the 8s or will they stretch out and look too loose? Any advice is appreciated.
