Have you tried Fabletics yet? I signed up in January and I've loved it since. It's kind of like a subscription service for workout clothes but you can skip as many months as you like without penalty.
I signed up for the VIP program because I earn reward points with every order and there's no obligation to make a monthly purchase. Every month I get outfits suggested for me based on my preferences (sport, colours, lengths, etc.) and I either make a purchase or opt out for the month. Easy peasy. Also? You don't have to buy an outfit they suggest. I've purchased outfits outside my referral range (because I wanted to try a different type of bottom) and I've purchased single items without committing to a full outfit. The program is extremely flexible.
I was concerned that the quality of the product would be low but I was happily mistaken. The leggings and bras are thick enough to provide ample coverage. The colours are bright and hold up to intense washing (I am ruthless with my workout gear. If I sweat in it, I'm washing it on the heavy setting.)
I've found a few annoying sizing discrepancies but nothing so serious as to warrant a return . For example, a pair of shorts I ordered one month are slightly smaller than the exact cut I ordered a different month. They're a bit tighter but not unwearable. It's possible I'm just being too picky (never!).
You can try Fabletics here (referral link! I get credits to use for future purchases if you complete a purchase using this link!) and if you sign up for the VIP program not only do you earn reward points you can use for future purchases, you can get your first outfit for only $25. My first outfit was a bra, tank, and capri leggings. For $25! And if you don't like the service, you can cancel immediately.
My favourites are: the Moro Short (I find this runs small so order up a size), the Forward Tee II (I have this in three colours and I wear it all the damn time. For working out, to work, around the house. I super heart-eyed smiley face love this shirt), and the Juneau Bra.
Do you use Fabletics? Do you love them as much as I do?
