onsie plus babylegs. they could also go under a dress like leggings or with bloomers (unless you're lucky enough to cloth diaper) with a top.
one of the biggest draws to me besides not pulling pants on and off is that these would have more potential for different fun designs and variety than you would find in pants, but at like $12 a pop, that goes out the window and i stop caring so much about pulling off pants.
enter raechel. her super simple and easy to follow tutorial shows how to take a $2 pair of target's women's knee socks and convert them into really well-made baby leggings. AWESOME!
yes, i went to the store the day she posted this tutorial and bought 8 pairs of target socks. but check out that selection. the colors! the patterns! all for what i would have paid for 1.33 pairs of pre-made ones (plus i like my patterns and colors better than the pre-made ones anyway)

the little cuff at the bottom will go over baby girl's heels or at her ankles if we still want to put shoes on her. even though these are longer than an actual baby leg right now, if i remember correctly, the whole fashion statement of the legwarmer was the scrunched-up look
i plan to stop by the sock department on every trip to target now and snatch up and new styles that come out so that our little girlie is always rocking a colorful, warm, homemade pair of babylegs! plus these totally count as separate items in my one-thing-a-day quest to clothe little girl.
